Constructing the aggregate queries looped through all objects in the session, even if no aggregates had been defined. This event was registered, just by importing `sqlalchemy_utils`, leading to unexpected side effects (slowdown) if a program loaded lots of models into a session.

construct_aggregate_queries()looping through all the objects in the session, even if there were no aggregates defined. Thus, this short-circuits that process if there are no aggregators registered.Fixes #700
