stack updated HBASE-14962:
--------------------------
Attachment: 14962.patch
Test gets RS and from here, it gets actual Region, doctors it so it can be
spied upon and then puts the spied upon Region back into RS list-of-regions.
This latter was being done by just getting the key of the 'first region'.
Sometimes the latter was hbase:meta.
