Updating a file can update the status now, so re-arrange this test.
This test really wants addon and files to have specific statuses, change
the order for it to work.
This changes because the starting status is no longer out of sync
Make this test file status follow the existing status of the other file attached
Get rid of the 'using' parameter in update_status(), it's now always on master
Fix ReviewHelper tests by reloading addon when necessary and updating status correctly on addon
Reset status in setUp after creating file
