Update touch mode regardless of mStopped

The very first state of touch mode is obtained from addToDisplay. It
should be applied in the first performTraversal regardless of mStopped.
In this way, when an app window is re-created at the background, the
touch mode state can still be up-to-date.

Fix: 227843343
Test: 1. Open Chrome and go to the homepage.
      2. Change the theme via the 3-dot menu > Settings > Theme.
      3. Go back to the homepage and see if any button is focused.
      Expected behavior: no button looks focused.
