Problem:

rpl_gtid.rpl_gtid_perfschema_applier_xa_status fails sporadically on
pushbuild.

Analysis:

The test executes XA PREPARE and then XA COMMIT on master.  After each
statement, it waits for the slave to sync, and then it checks that
performance_schema.events_transactions_current and XA RECOVER contain
up to date information.  The sync is done using
WAIT_FOR_GTID_EXECUTED.  However, the information is published in
gtid_executed before performance_schema and XA RECOVER.  So it is
possible that the test sees old information.

Fix:

Make the test wait for performance_schema information to be up to
date.  Then XA RECOVER is also up to date.
