emitter must be optional?

Hello.
In file Emitter.js you have

	stop()
{
	//Remove listeners
	this.emitter.removeAllListeners();
	//Free mem
	this.emitter = null;
}

in file SDPManagerUnified.js you have

	stop()
{
             ...
	//Stop SDPManager
	super.stop();
             ...		
}

But also you have method 'renegotiate'

renegotiate() 
{
	//Check if we already need to renegotiate
	if (!this.renegotiationNeeded && ["initial","stable"].includes(this.state))
	{
		//Set flag
		this.renegotiationNeeded = true;
		//On next tick
		setTimeout(()=>{
			//Clean flag
			this.renegotiationNeeded = false;
			//Emit event
			this.emitter.emit("renegotiationneeded",this.transport);
		},0);
	}
}

And there in setTimeout you may get an error, because this.emitter is null
