The key-values that the test is reading over.

I believe that the first tablet isn't being returned by the iterator which is causing the
2nd tablet (with a prevrow of "row5") to be seen as invalid.

> While attempting to write a test for ACCUMULO-3597, I found the master was not balancing.
 The iterator that filters the metadata table does not take migrations into account, so the
state of the tablets was never seen, and processed.  This bug was introduced with the fix
to ACCUMULO-3580.
