Don't do the IsOutOfDate or active_tab_is_ntp_ checks. It's entirely possible
that the hidden page will finish loading when Instant is in an out-of-date state
(for example, the omnibox has lost focus), and the user is on a regular, non-ntp
page. We still want to note the fact that it has a doodle.

Done.
