Properly collapse QQS header when QQS is disabled

In landscape, we need to fully hide the QQS when the user starts to do
an inline reply, otherwise nothing fits on the screen. This CL adds back
in some of the old Q behavior wherein we set the height of the header to
essentially zero when the QQS has been disabled (in this case, by the
inline reply logic).
