[TASK] Follow-up: Introduce native pagination for lists

- Switch the order of constructor arguments $currentPageNumber
  and $itemsPerPage of both the ArrayPaginator and QueryResultPaginator
  classes as the $currentPageNumber needs to be set on every object
  construction whereas the $itemsPerPage argument only needs to be
  changed for paginators that use a differen amount of items per page
  other than the default of 10.
- Change visibility of properties of both the ArrayPaginator and the
  QueryResultPaginator from protected to private as both classes are
  marked final.
