  Update RenderWidget's widget after transitioning from RemoteFrame to LocalFrame

Reviewed by Pascoe.

We already call setWidget when transitioning from LocalFrame to RemoteFrame, or no site isolated iframes would draw.
We need a symmetric update call when transitioning the other way for frames to continue to draw after cross-site navigations.
