Removed method BRepAlgoAPI_BooleanOperation::Modified2(const TopoDS_Shape& aS) as it is no longer relevant (in the previous version of BOP it had used History collector to find modified shapes, but there is no such collector in current version of BOP). The replacement for this method is BRepAlgoAPI_BooleanOperation::Modified(const TopoDS_Shape& aS). Small correction of test case
