Do not check for subsets when it is the universal set

can-fixture uses the memory store, but its super set is the universal
set. Therefore there isn't a need to check if a query is a subset. Doing
so causes errors when comparisons are made between unknown types.

This is part of canjs/can-query-logic#50
