Fix for search view/IME issues

- Set the search view as the custom action bar view on tablet too,
  (not as an acition view of a menu item.)
- Add a dummy view to the action bar to prevent the search view from
  getting the initial focus.
- Call SearchView.setIconified(false) to make sure the IME will pop up
  when setting focus on the search view.

Fix for:
- tablet: Keyboard keeps popping up upon app launch.
- tablet: Keyboard keeps going away after each character is typed.
- tablet: Have the search view request focus again.
- phone: Keyboard won't pop up when the search view is shown

Note:
- The width of the search view on the tablet is temporary until we
get redlines.
