eb0b3141d5 Fix aggregation functions on null and group-by inputs (#448) 
The `sum()` and `count()` functions were giving results different from the openCypher specification on null `input.` The aggregation functions also had a problem when they were used in a group-by context and were giving results that were not compliant with the openCypher specification.
