Handling References to other LogisticsObjects in add operations in Changes

This merge request addresses the issue #203 concerning the handling of links to other LogisticsObjects within Change ADD operations. Previously, the system treated references to other resources as embedded objects rather than IRIs leading to incorrect additions to the RDF repository. In particular, the links were converted to neone ids and RDF#type were added.

This patch modifies the applyOperations logic to recognize and handle these references as IRIs, ensuring proper linkage and data integrity in RDF statements.
