Tests have been migrated to the new api to prepare the migration of the
mail module itself. Moreover tests have been cleaned: redundant tests
and unnecessary tests have been removed.
As the base test class in mail is used in other addons, other addons
have been updated :
- portal
- project
- portal_project
- website_project_issue
- sale
- purchase
Future commits will come with somes fixes for issues detected when cleaning
the tests.
