Bug 1071706 - Dark icons on lockscreen r=mhenretty

Not really, what is waiting is for the longpress taking effect, not from pressing to the card view being shown. I thought the longpress was longer than 1 sec, but not sure why I come out with that number, though. 1 sec works fine as well, but longpress without time doesn't. I'll change it to 1 and will add a wait for the cards being shown just in case. Thanks!
