Occasionally we have to perform a migration only on the SQLite db and not the MySQL db or vice versa (see 00020_idx_db_directory). Up until now MySQL would fail though with "empty query". Since it's nice to have a nice overview of migrations I think we should allow empty migrations and not execute them when we find they're empty.
