Add test cases for WebRTC IP Permission check.

1. When permission is granted, with the default values, we should gather non-loopback candidates.
2. When permission is denied, iceServers passed in as [], we should not see any candidates.
3. When permission is denied, iceServers not specified, we should see loopback candidates only.
4. When permission is granted, but multiple-routes is not requested, we should see loopback candidates only.
