Update the node references when a renderer was created, so features like tracks
are querying the correct node. Otherwise for example the track files can't be found.

TODO: The features should look for the current active renderer instead of the node.
This current way has still a bug, when we switch between renderers that are already created.

@param event event with renderer node as detail when renderer was created
