David Baker ea39b69f65 Don't ignore ICE candidates received before offer/answer ...

The main bug here was a race on the callee side because we await-ed
on setRemoteDescription before setting the opponent party ID, and
while we were await-ing, the callEventHandler could give us candidate
events which we'd duly ignore because we thought the party ID didn't
match.

This also meant that any candidates that arrived before the answer
would have been ignored. Save these up by party ID and then add the
ones from the party ID that we pick once the answer comes in.

Also fix the confusion on party IDs where we weren't sure whether
we hadn't picked an opponent or we'd picked an opponent without a
party ID. It's now undefined for the former and null for the latter,
as it claims to be in the comment.
