Fix(db): Remove unused FOREIGN KEY REFERENCES in message_tags table (#374)

Browse Source 
This SQL patch rebuilds the message_tags table to remove the unused ID & TagID REFERENCES that was sometimes causing FOREIGN KEY errors when deleting messages (with tags) using the rqlite database. This is not a bug in rqlite, but rather a limitation of how Mailpit integrated with rqlite as an optional alternative database.
