This commit improve the daily use of activities by delegating activities
management to the document. Activities are already managed on document
through the UI either in form view or in kanban view.

Use case to reproduce:
- Set a product to be expensed
- Set the expense_policy to something else than no
- Do a delivery order with a picking
- Validate the picking
-> Delivered quantity to 0 and impossible to create an invoice
if the invoice_policy is delivered_quantity

It happens due to this commit 48ea59d4
What does it do:
- The move could be generated by an expense.
- If the move has 'no' as expense policy thus we won't add it in the invoice
Problem we can't guess if the move come from an expense or not (limitation).

This commit add an onchange on can_be_expense is order to set the expense
policy back to 'no' when the user uncheck it.

When opening the POS in this specific case:
- Under Mozilla Firefox
- auto printing the receipt is True
- invoicing is True

Before this commit, when issuing an invoice for a customer, a Traceback was thrown to the user and the invoice was not downloaded.
This was because the invoiced parameter resolved before the printing action was.

After this commit, we constain the invoiced parameter to be resolved when the action returns.
There is no traceback, and the invoice is downloaded

`tax_amount` is not defined here, making it impossible to remove an
order line...

- Create a tax:
  Fixed amount: 10
  Price included
- Add it by default to a product costing 100
- In a SO/PO/Invoice, add 2 units of the product

The total price is 210 instead of 200.

The `sale_stock.tour` failed in the case the admin was not
part of the group
`product.group_stock_packaging`
or the group
`sale.group_mrp_properties`

because then the sale order was working with the editable list,
which does not open a dialog,
while the test was relying on the dialog to be opened,
in order to close it.

The fix is simply to pass the fact to close the dialog if
there is none.

The link does not work anymore.
Even when it was, it did not provide any information as can be seen in

Do not try to run `action_assign` on the next move if it is done or
cancelled. The issue is that `action_assign` will first unlink the
existing pack operations before creating new ones, and the system
forbids to unlink these ones.

To reproduce this issue:
1. Create a product, routes manufacturing and MTO
2. Create SO with that product
3. Go to DO and force assign then cancel the delivery
4. Go to Manufacturing order created and produce

Suppose a tax of 20% with price_included = True and apply this tax on 399.99:
- base = 399.99 / 1.2 = 333.32500000000005
- tax_amount = base * 0.2 = 66.665
- round(base) + round(tax_amount) = 333.33 + 66.67 = 400.0 (!= 399.99: WRONG)

In 7eab8e26 res.partner was converted
to the new API, at that point company_type was changed from a stored
field manually synchronised with is_company (through create/write
overrides) into a proper computed field.

However to make it "editable" it was simply marked as
"readonly=False", which means even though UI-wise it looks editable
editing it does not actually do anything (things work in the partners
form because there's also an onchange which updates is_company on the
fly).

Fix by implementing an inverse function and actually do this
correctly.

Fields `amount_type` on `account.tax` and `account.tax.template` are
already defined in the `account` module.
Redefining them here (with the same parameters) breaks every other
module that would have used `selection_add=` on those fields.

Actually, it is the case in `account_tax_python`, and thus, all the
localizations/customizations that depend on it were broken by this one.

- Create an asset, post one line.
- Go back to the asset => the button is green
- Click again on the line => the button is orange

There is no protection to prevent the user to post the same entry
several times (a new account move is created every time it is clicked).

We fix the JS widget, but we add an extra layer of protection at the
Python level.

Before this commit, when trying to access website_public_price from the backend (when adding this field to a view for example), a traceback saying that the website attribute on the request object was non existent was raised.

After this commit, we control for this and the field displays correctly

Before this commit, when opening the POS in IE11, then the customer list, the list was empty.
This was due to condition that was wrongly evaluated as false due to the fact that IE11 apparently only wants ECMA5.1 to deal with constructing Date() from a string.

After this commit, we construct the Date() object with the right string, and the list of customers doesn't disappear.

Taxes tags for some localization have been rewrote in order to improve the taxes report.
However, these changes delete the existing account.tags on stable version.

These "[l10n_*] one tag per grid in tax reports" should target master instead of 9.0.

In some cases, vendor reference for payment may already exists.

For instance in Belgium, some suppliers provide recurring invoices which
contain the same communication for the payment. From the version 9.0,
the field Vendor refrence is used for payment communication and the
maching on bank statement.

So, in this case, we have to put the communication from the payment in
this field and, as explained just above, maybe the same as on another
invoice.

Therefore, this commit provides a hook to modify/disable this behavior.

The access to the state of sale.order.line (related field) seems very slow for big sale order. Bypassing the related field and using the real field instead, improves performance.
