    application: Fix the check to detect if we were the primary instance
    
    Reading the GApplication implementation confirms that the startup and
    shutdown signals are called (ie. an instance is primary) when:
      * GApplication:is-registered == TRUE
      * GApplication:is-remote == FALSE
    
    Fixing the primary instance detection will help prevent a CRITICAL when
    we handle local command line options (eg., --version) via the
    handle-local-options signal handler
    
    GApplication::handle-local-options is emitted before the local
    GApplication has had a chance to register. It will register only if
    handle_local_options returns a negative value. Otherwise, it will exit
    without calling g_application_register.
    
    When exiting, GApplication:is-registered is FALSE. Therefore, calling
    g_application_get_is_remote will lead to:
      GLib-GIO-CRITICAL **: g_application_get_is_remote: assertion
        'application->priv->is_registered' failed
