NgAudioObject destroy does not destroy object.

Hello,

I noticed that on a NgAudioObject is possible to call the destroy() method.
This method as far as I can see delete the timeouts and the watchers on the object.

function $destroy() {
            if (!$destroyed) {
                if (interval) {
                    $interval.cancel(interval);
                }
                if ($intervalWatch) {
                    $intervalWatch();
                }
                if ($audioWatch) {
                    $audioWatch();
                }
                $destroyed = true;
            }
        }

This LGTM since I can use this method to destroy an audio every time I want from a controller which import the ngAudio service, but then, I don't have a way to check if a NgAudioObject has been destroyed or not.

I see that once an NgAudioObject is destroyed, the internal variable $destroyed is set to true.
What if you expose also this variable on the NgAudioObject?
Something like this maybe?

this.destroyed = function() {
      return $destroyed;
};

I'd be happy to have a look at a pull request - if so, update docs as well accordingly.
