Fix rare scenario where outgoing WebSocket messages could be dropped.

Per the comment: At the end of pump(), while writing out pending auto-response messages, it's possible new regular messages could be queued concurrently. If we don't check for that, they could be discarded without actually being sent.

This is probably extremely unlikely and I have no evidence that it has ever happened. I noticed the problem while reading the code.
