Adds an after suite hook to manually clean Fedora.
Removes a single unneeded set from one spec.  Adds before/after suite hooks that go through and manually delete any object that our tests might be saving to Fedora/the database.  This doesn't seem to slow execution time at all, and is needed because the Fedora test repository does not seem to clean itself between runs.  Note that a more elegant solution almost certainly exists.

Feature/before after suite hooks
Remove unneeded puts statement in the destroy_incomplete_files action.
Adds a @incomplete_files instance variable to the provide_metadata action.  This cleans up some ugly processing code that had been written into the _metadata view.
