    albumwidget: Fix crash on switch back from search
    
    When switching back from search view Music crashes, because it does not
    receive the expected CoreAlbum from the 'album' property of AlbumWidget.
    This is probably fall-out from the core rewrite: AlbumsView expects a
    CoreAlbum, AlbumWidget supplies a Grl.Media.
    
    Have the 'album' property return a CoreAlbum instead.
