Don't restart certmonger after stopping tracking in uninstall
    
    certmonger was later restarted to remove the custom CA entries
    and the startup delay sometimes caused uninstallation to fail.
    
    certmonger is stopped in cainstance.py::uninstall() so it will
    still be stopped post-install.
