fix(non linear font scaling): date textview is cut off in qs header

Originally the qs header height is fixed to 120dp, so when larger font scaling the header height might not be enough to accommodate the subviews with given constraints, then some of the constraints are broken and the date textview bottom is cut off. Therefore, in NotificationsQSContainerController, we calculate the needed height for the subviews as the header height to prevent the ui broken.
