CallLogListItemViewHolder distinguishes block/spam numbers

A new method is added to show the appropriate photo and label
if the number is either blocked or spam. This occurs after the
normal photo and labels are rendered. Because of that, there is
a flickering if the photo and labels should be changed.
b/27295728 will help track the fix of the flickering bug.
