 We need to make the magic-folder db have a different schema; right now
 it's almost the same as the tahoe backup db schema... which is
 denormalized and uses several tables. Here instead we'll use just one
 table called local_files... it will contain version number, ancestor uri
 and ancestor timestamp but not the fileid field that tahoe backup was
 using.
