There were a few unit test files that didn't match their
code counterparts, so were a little hard to find. Moved
things around to line-up better, leaving only a handful
of exceptions to ignore. Added a test script to check
things so it won't happen again, copied from Neutron.
No actual code was changed, files were just moved around.
