BUG#43263 BEGIN skipped in some replicate-do-db cases

Browse Source 
BEGIN/COMMIT/ROLLBACK was subject to replication db rules, and
caused the boundary of a transaction not recognized correctly 
when these queries were ignored by the rules.

Fixed the problem by skipping replication db rules for these
statements.
