When performing an sms marketing on a model having only a ``partner_id``
field available (aka no ``phone`` or ``mobile``) it crashes due to seen
list computation (aka already contacted recipients). This is due to an SQL
query not taking into account those models as it works only for those with
a phone field.

We fix it as done in ``mass_mailìng`` app, aka fetching information on the
related partner if available.

Some tests for models using a 2many relationships towards recipients are
added. Note that this kind of model does not really support complete SMS
notification, as only the first found partner is notified. Mass SMS on this
kind of model is currently not possible as seen list is not supported. There
is no standard use case of this in Odoo codebase.

Correctly support sms marketing on sale model by defining the necessary
methods. As sale order has only a partner_id field available we have to
correctly override phone related methods for SMS.

Currently phone_sanitized computation on lead model works only if crm_sms
is installed. Indeed an override of ``_phone_get_number_fields`` is missing.
However ``_sms_get_number_fields`` coming with ``crm_sms`` and its ``sms``
dependency hides the issue as those modules are auto-install. However if
``crm_sms`` is uninstalled phone_sanitized is not correctly computed anymore.

PURPOSE

Purpose is to have more tests when sending sms mailings, notably about
canceled or failed mails or sms as well as jinja and links rendering.

SPECIFICATIONS

In this commit we improve SMS Marketing mailing tests. We notably

  * add tests for void and invalid email and numbers. It allows to check they
    correctly update their trace status;
  * add tests for unsubscribe and view links embedded in sms marketing;
  * add tests to simulate a click on links sent through sms marketing and
    ensure click statistics are effectively updated;
  * ensure content of sent sms are checked;

Default content of mailings used in test is updated to ensure jinja is
correctly rendered, including links and some corner cases. This will also
helps ensuring behavior is kept when converting to QWeb.

In event we now correctly use sms gateway mock to ensure SMS finding.

In link_tracker a helper is added to check url tracking in plaintext content.
