I reverted this change because I found references to the current (incorrect IMO)
trace name in other places.

                "FrameTreeNode id", frame_tree_node_->frame_tree_node_id());
   // Create a pending RenderFrameHost to use for the navigation.
   RenderFrameHostImpl* dest_render_frame_host = UpdateStateForNavigate(
       dest_url,
       // TODO(creis): Move source_site_instance to FNE.

       entry.restore_type() != NavigationEntryImpl::RESTORE_NONE,
       entry.IsViewSourceMode(), entry.transferred_global_request_id(),
       entry.bindings());
