Fixes to PeerConnection for Unified Plan sdp & transceiver logic.

This change includes updates to the sdp logic, and transceiver
dissociation and also tests these updates. The sdp validation for
unified plan is updated to consider both the stored remote and local
descriptions for an offer, because either could be the most up to date.
This is important when considering a recycled m section. This also
updates to only dissociate a transceiver when we are setting the remote
or local description from an offer. The final small update allows us to
properly create a media description for a transceiver that is not new
but is part of a recycled m section that has only been set locally for
an offer and we are re-offering.
