Keep a Photo's save path after its file leaves; refuse an empty download directory

A Photo now keeps the file its record was made from (the record projection holds one membership of each file), so savePath and isLocal still answer after a refresh removes the file. Library.open rejects an empty downloadDirectory. A backup clears leftover temp files in every date folder under its directory, not only in those of the files in its scope. placeOriginal no longer deletes what is at the save path before copying a live photo, and the tests that depended on that are removed. The TODO.md entry for issue 143 describes only the current layout. Model: opus-5-5
