resolve person count discrepancy

[fdefalco]

the achilles exported person.json file's SUMMARY attribute / ATTRIBUTE_NAME: "Number of Persons" ATTRIBUTE_VALUE is different from the value provided in the index.json / releases / release / count_person

You probably already know the reason but if not (and since I dug into it before I saw the bug posted): the number of persons in "Number of people" on the Data Source Overview page is based on the counts in BIRTH_YEAR_DATE in person.json (it's the sum of all those counts). Those come from Achilles query 3 but results of that query with a count smaller or equal to smallCellCount are not reported (in our case everyone born between 1887 and 1892). So the sum is lower than the actual number of persons in the PERSON table.
