REGRESSION(r186088): Crash under WebKit::WebPageProxy::didFailLoadForFrame 

For WKView apps:
This WebPageProxy methods calls m_loaderClient->didFailLoadWithErrorForFrame(), and inside that callback the embedding app can cause the WKView to go away.
When a WKView goes away, it's PageClientImpl gets destroyed also.
But then we call into m_pageClient, which was just destroyed...

So we'll add a refView and derefView method to PageClient, add a RefPtr-style object to manage those, and use it in any method where a loaderClient method is called but is not the last thing to be called in the method.
