make ntp apps promo work correctly

make ntp apps promo work correctly

when the promo is showing, use the promo link even if the user clicks on the icon rather than the promo button. Additionally, fix the referrer for clicks on the promo button (by using launchApp).

This lgtm, but are you sure we want to do this? I thought they the CWS wanted to
distinguish between the promo and the web store icon. And this now ties them
together ... which may or may not be a problem.

I don't think they want to distinguish between the icon and button. They want to
distinguish between when the promo is and isn't showing.
