Carlos Bentzen 48ae40f477 webrtcbin: create and associate transceivers earlier in negotation
According to https://w3c.github.io/webrtc-pc/#set-the-session-description
(steps in 4.6.10.), we should be creating and associating transceivers when
setting session descriptions.

Before this commit, webrtcbin deviated from the spec:
1. Transceivers from sink pads where created when the sink pad was
   requested, but not associated after setting local description, only
   when signaling is STABLE.
2. Transceivers from remote offers were not created after applying the
   the remote description, only when the answer is created, and were then
   only associated once signaling is STABLE.

This commit makes webrtcbin follow the spec more closely with regards to
timing of transceivers creation and association.

A unit test is added, checking that the transceivers are created and
associated after every session description is set.
