DescriptionPlzNavigate: fix nullptr bug in NavigationResourceHandler
The refactoring of the ResourceHandlers may have introduced a potential
nullptr dereference in NavigationResourceHandler::OnRequestRedirected
and NavigationResourceHandler::OnResponseStarted. This CL makes sure we
cancel the load and return early if the NavigationURLLoaderImplCore has
been reset.
