* Full reconnect on publication mismatch on resume.
It is possible that publications mismatch on resume. An example sequence
- Client sends `AddTrack` for `trackA`
- Server never receives it due to signalling connection breakage.
- Client could do a resume (reconnect=1) noticing signalling connection
breakage.
- Client's view thinks that `trackA` is known to server, but server does
not know about it.
- A subsequence offer containing `trackA` triggers `trackInfo not
available before track publish` and the track does not get published.
Detect the case of missing track and issue a full reconnect.
