Julien Fastré 9a9d14eb5a Enhance behaviour of duplicating storedObject to keep only the last "kept before conversion" version if any
Enhance the duplication service to selectively handle versions tagged with "KEEP_BEFORE_CONVERSION". Modify StoredObject to support retrieval and checking of such versions. Add relevant test cases to validate this behavior.
