correction_sorting()

This is a method to update/fix the sorting of the selected list of items.

The sorting will be done according to the queryset sorting, so sorting can be controlled by executing .order_by() before calling the correction_sorting method.

The selection for updating sorting can be pre-limited by filtering the list.
