[tor-commits] [arm/master] Cleaning up getHiddenServicePorts()

    Cleaning up getHiddenServicePorts()
    
    In my continuing effort to eliminate the _getRelayAttr() helper moving the
    getHiddenServicePorts() portion to its method. This also cleans it up a bit and
    fixes a use case where arm would crash with a stacktrace (if the
    HiddenServicePort target is just an address).
