Fix Hidden fields triggering error when using getSingleScalarResult() (#8340)
* Fix Hidden fields triggering error when using getSingleScalarResult() Fixes #4257 HIDDEN fields was causing the "unicity" check to fail (NonUniqueResultException), because we was counting raw data instead of gathered row data. * Fix Coding Standards (7.4) * Fix Coding Standards (7.4) #2 * Fix Coding Standards (7.4) - Fix whitespaces * Fix Coding Standards (7.4) - Fix whitespaces in tests * Fix Coding Standards (7.4) - Fix more things * Refactor tests into separate methods * Fix Coding Standards (7.4) - Equals sign not aligned with surrounding assignments
