    gnome-shell-perf-tool: Fix various problems
    
    * Fix wrong parameter name to on_name_appeared callbacks
    * optparse doesn't just leave extra command line arguments, it
      errors out, so don't try to pass through extra arguments -
      instead add explicit passthrough for '--replace'
    * Fix usage of Gio.DBusProxy
    * Add a default value for --perf so that if it's not supplied
      things don't die with a mysterious error message. (This wasn't
      needed when --perf enabled perf-mode)
