Findbox should disappear once we reload and open new tab and come back to previous tab.

This fix isn't correct. This breaks the following use-case:

1. Search in tab A.
2. Switch to tab B.
3. Switch to tab A.
4. Find count and highlighting should still be visible in tab A.

Thanks for review, I will modify my patch, considering this.

   UpdateFindBarForCurrentResult();
   find_bar_->UpdateFindBarForChangedWebContents();
 }
