Revert "Added PeerConnectionObserver::OnRemoveTrack."

This reverts commit ba97ba7af917d4152f5f3363aba1c1561c6673dc.

Reason for revert: The new tests have caused several test failures on the test bots; the method FakeAudioMediaStreamTrack:GetSignalLevel, which is not supposed to be called is sometimes called anyway.

Original change's description:
> Added PeerConnectionObserver::OnRemoveTrack.
> 
> This corresponds to processing the removal of a remote track step of
> the spec, with processing the addition of a remote track already
> covered by OnAddTrack.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
