Code review comment for lp:~rockstar/entertainer/trial-integration

This branch basically just makes all tests run by twisted's trial, which will
be required when for my next branch. The run_test.py script is gone, but if
you're like me, you've been using `make test` and in which case, you'll notice
only a difference in the output.

Also, tests needed to be renamed, and while I was at it, I consolidated the
tests from entertainerlib.frontend.medialibrary.music into one single file.
That's the extent of this branch.

The diff is relatively large, but only because there was the consolidation of
the music tests.
