    GtkApplication: Fix two muxer-related memory leaks
    
    Drop the ref on the action muxer in finalize, and also make sure
    shutdown() tears down the muxer setup done in startup().
    
    When GtkApplication adds itself to a muxer, it causes the muxer to take
    a ref on the GtkApplication. This has to be undone in shutdown() to make
    sure the GtkApplication doesn't end up holding a ref on itself.
