[IMP] test_mail: add new mail composer tests for its internals

Purpose is to have some low level tests for composer itself allowing to
ensure its behavior. We add tests notably about default values computation
in mass mailing mode as well as template_id change and values synchronization
in composer model.

In a near future composer will probably be improved (use computed fields,
rewrite part of its logic to improve performances). Having tests done before
those tasks ensure we notice every change that might happen.
