[TIMOB-2586] Android: AudioPlayer.setUrl causes exception

Our http://developer.appcelerator.com/apidoc/mobile/latest/Titanium.Media.AudioPlayer-object.html"> docs say that the way you set the Audio Player's url is with .setUrl. This causes an exception in Android (though it is possible to set the .url property instead).

Failcase:

var player = Ti.Media.createAudioPlayer();
player.setUrl('x');

will cause an exception which you can see in logcat (trace log):
