Call log item layout changes for selection highlight.

Move the quick contact badge into the primary action layout, so that the

Delete the no-longer-in-use unheard image view.

It might be possible to flatten one level of the hierarchy by removing
the RelativeLayout, but I will look into that in a follow-up.
