Make private properties more private

[calebboyd]

I ran into this issue when trying to load Twilio on the iPad.

Referring to these properties specifically:
https://github.com/eface2face/cordova-plugin-iosrtc/blob/master/js/MediaStream.js#L66-L70

Twilio has a method that looks like this:

PeerConnection.prototype.attachAudio = function(callback) {
        if (this.stream) {
            var audioTracks = this.stream.audioTracks || this.stream.getAudioTracks();
            audioTracks[0].enabled = true;
        }
        if (callback && typeof callback == "function") {
            callback();
        }
}

As you can see it errors when accessing the [0].enabled property of this.stream.audioTracks

I've filed an issue in Twilio to prefer spec.. But it would probably be good for the module hide its private state better anyway.

Also.. Thank you for a great plugin!

Why is Twilo calling stream.audioTracks? A MediaStream does not have such a property...

I have no idea -- it is pretty odd... I'll let you know If I hear back from them on the matter.. Thanks for making that change

Prior to Chrome 26, audioTracks was a property on MediaStream. Chrome 26 introduced the getAudioTracks() method. The compat code could probably be changed to

var audioTracks = typeof this.stream.getAudioTracks === 'function'
  ? this.stream.getAudioTracks() : this.stream.audioTracks;
