If leads are created using live chat, users without CRM rights cannot
access the visitors list anymore because the lead/opportunity
information is not available to them.

This commit limits the display of `lead_count` to the
`sales_team.group_sale_salesman` group.

In 14.0, the column still appeared without the `lead_count` value
displayed, but clicking on it raised a traceback.

Steps to reproduce:
- Install `website_crm_livechat`
- Login as Mitchell Admin
- Send a message in the live chat
- Go to Discuss
- Answer the livechat message with `/lead New`
- Go to Settings / Users / Marc Demo
- Remove the Sales rights
- Logout
- Login as Marc Demo
- Go to the Website / Reporting / Visitors page

=> The page could not be reached and an access right error message was
generated.

Depending on the modules installed, the action of the form on the
`/contactus` page changes. For example, if you have `website_crm`
installed, the action will be set to "Create an Opportunity" but if you
only have `website_form` installed, the action will be "Send an Email".
For each action, there are mandatory fields that cannot be deleted by
the user. Unfortunately, the templates for the `/contactus` forms didn't
have the right fields marked as mandatory. This led to the following bug
(with only `website_form` installed):
- Go to `/contactus`
- Edit the page

=> The Email and Subject fields can be deleted. However, when you drop a
form and set the action to "Send an Email", these fields are mandatory
and cannot be deleted. This commit fixes this bug by ensuring that these
fields are marked as mandatory on `/contactus`. This commit fixes the
same issue with the `website_crm` module.

Currently stat button on crm.lead form view still shows page views count of
archived visitor records. This is not coherent with the action performed
when clicking which filters out archived records.

We now correctly count only active visitors page count.
