Fix Races in testQueuedSnapshotOperationsAndBrokenRepoOnMasterFailOverMultipleRepos (#62431) (#62614) 

This test (in-part) verifies that snapshot creation is not
retried on master fail-over once a snaphot has been started already.
Unless we wait for the snapshot creation to show up in the cluster
state before failing the master node though, we could run into a
race where the snapshot wasn't yet in the cluster state and a retry goes through
successfully.
