[reynaldichernando]

WARN new NativeEventEmitter() was called with a non-null argument without the required addListener method.
WARN new NativeEventEmitter() was called with a non-null argument without the required removeListeners method.

Issue #455

Is this a breaking change or just a warning? I'm trying to figure out why voice is not working.

Edit for reference: not a breaking change that I could see, voice still worked despite the warning

Can someone with write permissions approve this? (eg. @carlmagumpara I think, among several others)

Adding these methods resolves the related RN warnings. This is not a breaking change since it does not implement any functional code changes or modify dependencies.
