[Flakey Tests] branch-2 TestRefreshRecoveredReplication.testReplicationRefreshSource:141 Waiting timed out after [60,000] msec

This one fails for me most times running locally.

I added some debug (see the PR).

In the test we look for old replication source to be non-zero long after it has been processed. The test gets stuck waiting.

See here is where the table becomes available, after which we start expecting the old source replication queue to be non-zero.

{{ 2020-12-01 20:02:52,400 INFO [Listener at localhost/56996] regionserver.TestRefreshRecoveredReplication(136): Available testReplicationRefreshSource}}

 But see here where the replication source has been removed before we get to the 'available' line above:
