[gnome-shell] dnd: Don't try to remove an invalid idle source

    dnd: Don't try to remove an invalid idle source
    
    As the handler returns false, the corresponding source is removed
    automatically and its id invalidated. Reset the id to 0 to reflect
    this, otherwise newer versions of GLib will print a warning when
    we later try to remove it explicitly.
