MDEV-32779 : galera_concurrent_ctas: assertion in the galera::ReplicatorSMM::finish_cert()

Browse source 
I could not reproduce reported assertion. However, I could
reporoduce test failure because missing wait_condition
and error in test case. Added missing wait_condition and
fixed error in test case to make test stable.
