    Don't try to register for unique bus names in remote instances of Empathy.
    
    This means, that remote (secondary) instances of Empathy won't try to hold the
    Chat or FT bus names (which will always fail.
    
    It also means that remote instances don't try to hold the GApplication (though
    they would release it upon exit anyhow).
