Review comment:
It looks like this code checks to see if the tablet has a currently
assigned location, and *only* if that currently assigned location is *NOT* also
hosting the metadata for that tablet's own metadata, then the tserver is okay
to shutdown.
However, it seems like there are two problems with this:
1. the tserver could still be added to the list if another tablet adds it,
so it could still cause problems, and
2. this could result in no tservers shutting down, therefore not actually
checking the conditions the test is intended to check
