The test that triggers multi-master conflict between two CTAS commands uses LOCK/UNLOCK TABLES to block local CTAS from progress. It could result in a race when UNLOCK TABLES command is issued a bit earlier then needed, causing local CTAS to run further and change wsrep transaction state, so that a different code path is taken later and the original error gets overridden, causing the test to fail. The solution is to replace LOCK/UNLOCK TABLES with debug sync points. Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>
