This is a follow-up to https://codereview.webrtc.org/1965313002/ which was TBR-landed. Minor code clean-up/corrections: Property nativeConfiguration -> - method createNativeConfiguration. RTCLogWarning -> RTCLogError. setConfiguration returning NO instead of false. initWithFactory returning nil instead of nullptr. Braces around ifs.
