Why any changes to this file at all?

I figured this change would be needed eventually to update the microphone (same
for instant_page), however I'd be fine leaving this for the follow-up CL.

No, by going through SearchTabHelper, now Peter's change only needs to listen to
SearchModel changes via the observer. So the changes to InstantPage and
InstantController are not necessary.

I see.  Reverted changes.
