12.2.1.RELEASE

Fix for total count of filtered task list result (#1512)

* added Query utils to detect if query to be executed concerns a count query, if so skip providing groupBy

* switched to single result for count query

* added copyright header

* removed distinct from list query as this is not necessary

* added additional todo for performance improvement

* distinct is not necessary when also having a group by
