[IMP] mail: tests: improve / add common classes and data for mail tests

This commit improves common classes and add helpers for mail tests.
Future commits will use this new stuff to improve the tests.

 * improve existing models and add some of them. There are now several
   models

  * mail.test.simple: chatter-enabled record without any really advanced
    feature. Can be used everywhere standard chatter and communication
    tests are required;
  * mail.test.track: chatter-enabled record with basic value tracking
    and responsible tracking;
  * mail.test.activity: chatter-enabled record using activities;
  * mail.test.full: complete chatter-enabled record with advanced
    tracking, automatic subscription and automatic email send based on
    templates and tracking;
  * mail.test: chatter-enabled record having an alias. It can be used
    where umbrella record like projects or teams has to be used in
    tests;

 * add MockEmails test class: this class mocks the mail gateway so that
   tests can work on emails without actually sending them. It is taken
   out of TestMail class to clearly separate features from class;
 * improve created data in the various classes and prepare work to
   lessen created data during tests;
 * add helpers on base test class, notably

  * sudoAs: context manager to run a code snippet using a given user;
  * assertNotifications: assert notification content, aka Inbox or email
    notification and their content; may be subject to change depending on
    mail evolution;
  * assertEmails: check content of sent emails;
