Proper message should be displayed when no records in
attachments kanban view when we click on 'File' stat
button on product form view.

Change the external_layout_header, with the use of
span tag and display inline-block property instead
of div tag, because without using it, the address
under-line occupied the whole col-xs-6 block, for
small address also. By using display inline-block
the length of address underline will same as length
of address. And col-xs-6 will increase the address
space for log address lines.

When creating a partner, the fields where the information is not specified were
filled with an empty string value.
The empty string value is not ideal as prevents to use filters like "email not
set" and forces to use more complexe domain "... or email = ''"

Instead, set the value false for the fields were nothing is provided (same
behaviour as backend web client).

Remove the fields.barcode overwrite to empty string as it is probably an
unintentional side effect of 3b33e5c3.

This method is not very useful. Why ? When any exception is raised, odoo will rollback
all the transaction which were not committed, hence the purpose of the method won't be
served, which was, to update the 'history' record which was created before an invalid
action was performed.

    - removed fields of 'res.partner.job' and 'res.partner.contact' models
    - removed non-stored compute field 'base' of model 'account.invoice.tax' from anonymization list
    - removed fields 'tax_amount' and 'amount_taxed' which no more exists in 'account.move.line' model
    - removed field 'check_total' which no more exists in 'account.invoice' model
    - removed field 'partner_phone' which no more exists in 'crm.phonecall' model

No behaviour changes, only migrate code and add
some docstring.
