Fix timing issue with OnDraggableRegionsChanged 

When bfcache is disabled use the RenderFrameObserver::DidFinishLoad notification
instead of the DidStopLoading notification that originates from the browser
process. During fast navigation the DidStopLoading notification may arrive in
the renderer after a new navigation has commenced and cause the wrong regions to
be reported.
