* Add some constraint at database level Fixes #79 and should fix #201 and #113 as well * Fix tests Delete duplicated data before adding constraints (only with Postgres, there is no way to do it with Sqlite with complex constraints like the one we are using) Remove the constraint on media path * We don't need to drop the media unique constraint anymore Because we deleted it
