Christopher Tubbs resolved ACCUMULO-3580.
-----------------------------------------
    Resolution: Fixed

Added the fix to 1.5 and later branches. Added a test for 1.6 and later, because it was easier to write the test in 1.6.

> I was examining -Xlint warnings and found this warning about a fall-through case in a switch statement:
> The {{TabletStateChangeIterator}} in the master does not properly skip over tablets which are hosted and online and have no work to do. This probably makes the master handle these when it doesn't need to.
