If patchwork URL has a port on it, sending requests will fail

Add port to URL when sending requests in patchwork/Connection.py
```
l70       if self.__port:
l71            return f"{self.__scheme}://{self.__hostname}{self.__path}:{self.__port}{url}"
l72       else:
l73           return f"{self.__scheme}://{self.__hostname}{self.__path}{url}"
```
