[IMP] test_mass_mailing: add blacklist mixin tests

Purpose of this commit is to add some tests linked to the blacklist mixin
itself, notably the computed fields and its search method.

This commit is related to task ID 33224 (original blacklist implementation
done for v12) and its PR #25966 as well as task ID 1889703 (tests and fixes)
and its PR #27330. Done with collaboration of @dbeguin.
