Subject: [PATCH] MDEV-28953 sporadic failures with
 galera_sr.mysql-wsrep-features#165

Modified galera_sr.mysql-wsrep-features#165 test to be deterministic:
Added one wait condition to catch execution state after --send command.
Changed another wait condition to better match the execution state of the test thread.
