Purpose of this commit is to add some test about MailThread helpers built on
top of ``message_post`` / ``composer`` (log, post with view, ...). Some tests
about batch are also added.
Some performance tests are also added for those helpers.
Counters are updated. Note that they did not change, it is just an update
based on current master counters.
