Instant interactive_ui_tests should wait for main frame load.

Instant interactive_ui_tests should wait for main frame load.

Before this patch, instant search tests didn't wait for the main frame load before executing javascript, resulting in running javascript in incomplete document.

This patch is to allow reland of v8::context patch in blink: https://codereview.chromium.org/263583002/
It seems that the valid document were luckily there when we run these tests before the blink CL, but the blink CL changes the timeline so it fails on these tests.

PTAL. New fix seems to be working.
