[totem-pl-parser] Fix returning FALSE with no error set in _save()

[Bastien Nocera <hadess src gnome org>]

commit 09b2bae800f5505b65c055ce9fd2f8b8d5daf265
Author: Bastien Nocera <hadess hadess net>

    Fix returning FALSE with no error set in _save()
    
    When the playlist is empty, set an error mentioned why it failed,
    instead of failing silently and not setting the error.
