Fix ConcurrentSnapshotsIT.testMasterFailOverWithQueuedDeletes (#60307) (#60376) 

The test assumed that the master fail-over would always work out as a single step.
This is not guaranteed however and we can randomly see master failing over twice,
in which case the transport listener will be failed on the node that stops being
leader and we have to catch an exception for the deletes as well just like we do
for the snapshot.

Closes #60262
