test(historian): wire test expects the Gateway's default aggregate set without TimeAverage/Total (lmxopcua#746)

The H2 merge (0b85c499) stopped advertising native Gateway TimeAverage/Total
until historiangw#27; it updated the Host test (4e76eeb5) but not
AdvertisedAggregateFunctionsWireTests, which failed 2/7 on master.
