[FLINK-6293] [tests] Harden JobManagerITCase
One of the unit tests in JobManagerITCase starts a MiniCluster and sends a
LeaderSessionMessage to the JobManager without waiting until the JobManager
has gained leadership. This can lead to a dropped TriggerSavepoint message
which will cause the test to deadlock.
This PR fixes the problem by explicitly waiting for the JobManager to become
the leader.
