Bug 1622384: Implement stable indexing for JSEP transceivers. r=mjf 

JSEP transceivers were previously held in a vector, in the order that they were
created. However, these could be removed, which meant that the indexing was not
stable. Under most circumstances this did not matter, however there was a
wrinkle with implicit rollback in repeated sRD. Re-applying a remote offer that
had created a transceiver would destroy that transceiver, and create a new one
to replace it. However, JS was not informed, because to PeerConnectionImpl it
looked like nothing had changed. Now, transceivers are indexed in a stable way,
which allows this bug to be fixed, and makes things a little less confusing.
