Don't re-determine ICE role on an ICE restart.

This only causes an increased likelihood of role conflicts as each peer
is picking a new role. It also means that if ICE is restarted for only
one media stream, roles can be different across media streams (which isn't
even allowed).

For more explanation of why this is unnecessary and should be changed,
see this discussion:

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. This page is maintained by the Google Chrome team.

Development

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