In CTAS, handlers get registered under statement transaction (st_transactions::stmt), while ha_fake_trx_id(), used by CTAS, looked under standard transaction (st_transactions::all) for registered handlers, and thus it failed to grab a fake transaction ID. As a result, with no valid transaction ID, wsrep commit failed with an error. ha_fake_trx_id() now looks for handlers registered under 'stmt' in case 'all' is empty. Also modified the logic to print warning only once if none of the registered handlers have fake_trx_id.
