When opening a new tab by pressing CTRL-T in app mode, the location bar would not get focused. This is because when the tab was shown its browser window is not yet active.

BUG=6380
TEST=Open an app (ex: gmail), press CTRL-T, this opens a new browser with a new tab. Navigate to google.com in the new tab. Go back to the app, press CTRL-T again, a new tab should be opened and the location bar should have focus.
