Fixing delta api for account removal case.

Account removal uses a different code path from normal contact deletes.  This
patch properly adds deleted contacts into the delete log when an account is
removed.  Also updates contact last updated timestamp for the non-delete case
when a raw contact is removed from an aggregate contact.
