starhandlerwidget: Update call for new SongsView._songs_view name
With the template port of SongViews (MR !711 (merged)), SongViews._view has been renamed to SongsView._songs_view. The call from starhandlerwidget has not been updated to the new name, causing Music to crash when trying to favorite a song from the songs list. This fix the crash by using the correct name.
