I'm trying to switch away from self to bind(this). Ben Kalman prefers that style
and extension_options.js has been using that style and so I think we should
adopt that style for consistency.

  PluginDestroyedEvent.addListener(function(e) {
    this.webViewInternal.onPluginDestroyed();
  }.bind(this), {instanceId: this.viewInstanceId});

Done.
