Bug === When we called assertMailNotifications in batch, with different notification status, it might raise an error when it shouldn't. The reason for that is we check that no mail at all are created, for the entire batch instead of filtering on the related partner. `assertNoMail` should only check if no mail are created for the partner it receive in arguments.
