Title: cleanups to the existing test suite

This adds no new behavior. These are cleanups to the test suite
to get it up to modern Assert testing style/standards.

In the process of cleaning up, I noticed the file store tests were
not very robust. I updated the tests and in the process changed
the internal API for accessing a "null store" object.

@jcredding ready for review.
