Added unit test to excercise the code that checks the consistency of the metadata table during GC scans. Also added a check to ensure the last tablet was seen. This should cause an error to be thrown if the scanner stops returning data for any reason. These changes were already made in 2.0 in apache#1266. However the code in 1.9 is so different that they could not be backported, but had to be reimplelmented.
