+ Rename some logic around identifying the scenario (tab vs activity)
for the call log.
+ Add padding at the bottom of the call log.
+ Make call log in tab show all history, not just recent history.
+ Rename promo card logic in CallLogAdapter, since it is VM specific.
- Remove extra view holder, and associated logic.
