localrepo: use dirstate restorebackup instead of copying dirstate manually This is one step towards having dirstate manage its own storage. It will be useful for the implementation of sqldirstate [1]. I'm deleting two of the dirstate.invalidate() calls in localrepo because restorebackup method does that for us.
