The idea of Thunar --daemon is to have it running as D-Bus service,
possibly w/o any active window. So there's is little use in setting the
restart hint to RestartImmediately, since D-Bus already auto-starts
Thunar anyway as required. Having both xfce4-session and dbus-daemon
restart Thunar doesn't sound like something one should do.
