This reverts commit 65c0a60302202189c37af91fca6abf092f022b1c.
Reason for revert: Breaking downstream test which was calling CreateAnswer in stable state. Will reland after fixing test.
Original change's description:
> Parameterize PeerConnection signaling tests for Unified Plan
>
> This also changes the behavior of CreateAnswer to fail unless
> the signaling state is kHaveRemoteOffer or kHaveLocalPranswer,
> as per the WebRTC specification.
