Rebuild on lifetime extended update

Rebuilds the notification when a lifetime extended notification has a
system update sent to it. Without this, an app that cancels a
notification a second time after a direct reply has already occured and
the notification is lifetime extended will see a second update sent (one
on the direct reply, and one on the cancelation),
which will clear any remote input history items from the notification.
