Fixing broken clear focus behavior.

1. In a prevous patch I fixed the issues when on clearing
   focus of the first focusable view the callback for
   gaining focus were called before the ones for losing
   focus. Since it cause some issues the patch was reverted
   and resubmitted. In this chaos some code was missed so
   tests are failing. Added the missing logic to give focus
   to the first focusable in the current touch mode when
   a view loses focus.

2. Removed clear focusForRemoval methid since it is a dup
   of unFocus();

Note: All focus tests now pass.
