for a very long time, if a remote server responded to us with
a valid but unsuccessful (HTTP 4xx) response and the caller was the
`send_federation_request` function, we may find ourselves
with a warning message only containing the destination's
server name which was very unhelpful. the true error was
buried away in trace logs. this would primarily be noticed
with server key fetch requests from us.
