Revert "Add transaction id to CandidatePairEvents."

This reverts commit c308bdfa451ee2ceac7096b6777fcbf756f4091a.

Reason for revert: The msan bot has been consistently failing since this commit. See eg https://ci.chromium.org/p/webrtc/builders/luci.webrtc.ci/Linux%20MSan/16989

Original change's description:
> Add transaction id to CandidatePairEvents.
> 
> The transaction id is a randomly generated number used to link stun
> requests and responses (https://tools.ietf.org/html/rfc5389#section-6).
> Logging this will help us debug ICE network issues.
