Elt.OnAfterRender() is missing a dependency on OnAfterRenderControl

[Tarmil]

Original report: https://forums.websharper.com/topic/85970

When using .OnAfterRender() on the server side and not directly using any other client-side code, WebSharper.UI.js itself is not included, which results in the following JavaScript error in the activator:

Uncaught TypeError: Arrays.get(...) is not a constructor

and the OnAfterRender callback is not called.
