Fix a bug where custom cards are not refresh when removed

When the last custom card for a specific type is removed,
onContextualCardUpdated should receive the cardtype info so we can
remove it from main data set.

- Reverted onContextualCardUpdated method signature back to before
- Force ConditionContextualCardController to send an empty list if
  everything is removed.

* Note: the update logic is pretty complicated to handle
  add/update/remove all together. In the future we should consider
  spliting the removal logic to simplify this area.
