Repro:
1. Search for "anderson cell" in omnibox
2. Quickly after serp started loading, click on "message" link underneath the venue listing

Expected: intent to IM/SMS handler on the phone
Actual: fallback intent is invoked inside browser

I tracked down that the issue is happening because RedirectHandler.java is getting "false" as user_gesture_carryover parameter when we click on the page soon after load. Need to figure out why we have a discrepancy between page still loading and finished loading here.
