Crash in WebKit::WebPageProxy::resetStateAfterProcessExited when destroying

I'm not sure what changed here, but we have a very frequent UI process
crash that's triggered by a web process crash. If the web process
crashes shortly before or after the user closes a web view, then the
PageClient has already been destroyed, and WebPageProxy::pageClient will
return nullptr. We need to null check before using it, a common pattern
throughout WebPageProxy.
