Unlinking a model during uninstallation can potentially fail when the query
removing any related mail activity types fails. This happens when such a record
is still referenced in the mail_activity table. Explicitly removing related
mail activities (as is done for the activity types and other related mail data)
resolves the issue.
Two tests are added, one that demonstrates the general flow and a regression
test triggering the behavior that caused a bug in the uninstall procedure of
the hr_holidays module.
