the initial replay body, circa the usage of our "compatibility" layer (4b53081, #3598), used to need an extra poll to confirm the absence of trailers before it would report itself as reaching the end of the stream. these tests were added in (afda8a7, #3583).
this was an artifact of how the compatibility middleware masked the previous
poll_data()andpoll_trailer()methods behind a forward-compatiblepoll_frame()- andframe()-oriented interface.this commit removes these extra calls to
initial.frame().await, now that the initial body will report the end of stream without an extra call to await aNone.ReplayBody<B>withFrame<T>#3598
