Fix foreign key constraint: delete mail_objects before mails

Browse Source 
Added deletion of mail_objects before deleting mail_messages to
avoid foreign key constraint violation. The mail_objects table
has a foreign key to mail_messages.

Complete deletion order:
1. Clean up auxiliary tables
2. Unlink mails from jobs
3. Delete mail_objects
4. Delete jobs (cascades to runs)
5. Delete mails
