code coverage QoQ doesn't account for nulls in sum()
Description
This QoQ in the code coverage
makes the incorrect assumption that if there are results from the QoQ that they will contain numeric values. But an empty result set will have one row with nulls which is proper SQL behavior. Lucee's QoQ didn't. Adobe CF doesn't follow proper SQL behavior here ( https://tracker.adobe.com/#/view/CF-4211230 ) but Lucee Server does as of 5.3.8
