[Android] Ensure omnibox suggestions reappear after refocusing Chrome.

When losing window focus, the omnibox suggestions are removed
and when bringing back focus to Chrome they are not redisplayed.

We should retrigger the omnibox suggestions when bringing
Chrome back to the foreground when the url bar retains focus.
