Summary:
When unrealized item is focused, edje object is not exist,
so genlist cannot read the focus highlight information from edje object.
Therefore, when the item is realized, check the item is focused or not and
need to update focus highlight.
@fix
Test Plan: change edc for supporting focus highlight in edc, and set focus on unrealized items.
