[FIX] mail: adapt forwardported tests

The ChatManager has been refactored in saas-11.2 to make it fully
(and more easily) testable. This means that tests involving
messaging stuff written in previous versions need to be slightly
adapted when being forwardported to saas-11.2. In particular, the
3 tests adapted in this commit broke because of an include done in
the voip addon. Those tests have been added in 3809fc891.
