Subject: [PATCH] ScreenShield/MessageTray: fix crash after the introduction of
 close buttons

Commit 5c6b1fd0c modified the hierarchy of SummaryItem contents, by
introducing a notificationStackWidget in place of the StackView, but
forgot to update the bits in ScreenShield.NotificationsBox that accessed
and reparented that directly, causing a crash by invalid theme node access.
