Check cascading of partOf named areas (throws NUOE e.g. in CoL import)
Currently the CoL distribution import throws a NonUniqueObject exception during the 1000-2000 partition with TDWG 12 (South East Europe) being the non unique object. The area itself is never imported. However, it seems that it is added to the session via cascading from multiple child (or parent) areas.
This seems to be incorrect from the import algorithm side but also we should think about removing cascading from partOf, kindOf, generalizationOf, includes. These terms should probably be saved on there own, not via cascading.
