A few additional fixups for adding TRUNCATE triggers.
-Do not call the deprecated/removed replica_truncate_trigger/origin_truncate_trigger function
-Have the unit test use the proper syntax for a cascaded truncate
-truncate triggers do not show up in the information_schema (at least up to 9.1).
 query pg_trigger directly to check if the truncate triggers exist.
