[60629] Display messed up after creating child from relations tab in split view

What are you trying to accomplish?

After creating a Child via the relations tab from split screen, the page layout was completely broken. This happened because we use redirect_back in the children creation controller to refresh the page that called the dialog. For whatever reason, this is however not a complete reload as the angular uiRouter is not triggered. Thus, the bodyClasses are missing and the page layout breaks.
This PR adds the bodyClasses on turbo:load which is somehow circumventing the actual problem as it is not turbo related. However, the turbo:load event is fired when redirect_back is called.

This seems to work at the cost of an extra reload but I'm a bit too far away from frontend to tell if that's correct or not.

There is no extra reload.. The turbo:load event is fired anyway. I just add classes to the body when that happens
