    places-view: Fix regression
    
    Unlike NautilusFilesView, NautilusPlacesView is not a subclass of
    GtkGrid, but instead it's a subclass of GtkBox.
    
    Casting it to GTK_GRID fails at runtime, showing the Other Locations
    view as empty.
    This is a regression caused by e9ae1add9cccee61d10e724b3d7f3526df8ad32a
    
    Fix it by treating it as a GtkBox.
