[issue14740] get_payload(n, True) returns None

Thanks for the report and patch suggestion, but...

This is actually the way it is designed to work.  get_payload(i) returns the ith element of a multipart payload.  Your workaround is in fact the correct way to do this operation.  decode=True is documented to return None if is_multipart is True.

You will note that if decode=False, you get back the Message sub-object, not a string.  Since decoding a Message object (as opposed to its payload) is not a meaningful operation, None is returned for decode=True.  Arguably we should raise a TypeError or ValueError instead, but we don't for historical reasons.
