    Connect to accounts service correctly
    
    Previously, we were using
    
    dbus_g_proxy_new_for_name_owner which is wrong,
    since that command will fail if the service isn't
    already running.
    
    (This used to work because we also do a separate
    dbus_g_proxy_new_for_name to the accounts service
    in a different source file that happened to be getting
    run early enough before)
