Test the case where the client makes a post KIP-74 FetchRequest, but the server replies with only a
partial request. For v3 and later FetchRequests, the implementation of KIP-74 changed the behavior
so that at least one message is always returned. Therefore, this case should not happen, and it indicates
that an internal error has taken place.
