Subject: [PATCH] Fixed HorizontalListView child element layout not being
 measured on layout change.

Changes to the size of view elements within one of the child views were not being reflected on screen (until scrolling the element out and back in).
The issue was the HorizontalListView onLayout call wasn't re-measuring the child view in onLayout.
This meant that if updating a TextView with a longer text, the text was being truncated.
