Purpose is to test specific behavior of opt-out for SMS marketing. This is
currently not tested and working a bit strangely, as they are flagged as
blacklist. This will soon be updated in another task but at least current
behavior is logged somewhere.

We also update some test models in order to reflect potential strange and
non-default behavior, notably partner_id field used as contact field. It
will be used soon when cleaning some opt-out behavior.

Tests are added to check phone sanitized is correctly taken into account
in default domains when inheriting from the phone blacklist mixin.

Some counters notes are also updated next to some last updates.

Task ID-2431217
COM PR odoo/odoo#71140

Purpose of this commit is to improve and add tools, methods and data to test
mail and SMS features. We also add tests for current implementation of SMS
feature, allowing to better understand future changes.

[ADD] test_mail_full

  * have a module depending on mail sub-applications like sms or snailmail.
    Its purpose is to check that standard mail features work effectively with
    all overrides and extra behaviors activated;
  * add a new model specific for SMS gateway, with default recipient
    computation;
  * add SMS tests for SMS module adding SMS capabilities linked to mail
    feature. This commit tests SMS feature before the upcoming refactoring
    and improvement of SMS module in community: posting with SMS and sms
    composer usage;

In test_mail

  * add necessary mobile information on test partners;
  * improve assertBusNotification that was not correctly asserting all items
    in message of bus notifications;

In sms

  * add mock for SMS sending. Purpose is to mock the connection to IAP
    services by mocking the call to IAP server. It allows to perform SMS
    tests without having to contact (and pay) for this service;
  * allow some customization when calling the SMS gateway mock to simulate
    errors and test corner cases;
