Create a new expansion function, expand_loose_notes_ref which will first check whether the ref can be found using get_sha1. If it can't be found then it will fallback to using expand_notes_ref. The content of the strbuf will not be changed if the notes ref can be located using get_sha1. Otherwise, it may be updated as done by expand_notes_ref. Since we now support merging from non-notes refs, remove the test case associated with that behavior. Add a test case for merging from a non-notes ref.
