[iOS] dataChannelDidChangeState crash

See original GitHub issue

Hello, after this PR https://github.com/react-native-webrtc/react-native-webrtc/pull/919 (issue https://github.com/react-native-webrtc/react-native-webrtc/issues/917) I have a crash when a connection is made. Specifically the crash occurs in dataChannelDidChangeState in RTCDataChannel.m : a NSDictionnary is created with the channel id but channel.originDataChannelId can be null. Note that it doesn’t always happen so it looks like a race condition.

Expected behavior

Connecting to a peer should not make the app crash randomly on iOS.

The PR is now ready and the test @ibc posted works just fine. I also fixed some more corner cases when closing datachannels.
