Reuse same labels and containers on notification updates

When calling Notification.update, reuse the previous _bannerBox and
related labels (only changing the label content and relayouting), so
that the opacity set on popOut is preserved. As a consequence, updating
an opened notification no longer shows (or flicker) the banner at the
top.
