bug#25470: 26.0.50; Lock files not removed when auto-save-visited-file-name is t

[Philipp Stephani]

Customize auto-save-visited-file to t, then edit a buffer and wait until
it's auto-saved.  Even after auto-saving the lock file (.#) is still
present.  It should be removed after a successful auto-save.
