Putting the optional clause within the graph clause causes to query causes,
using DEV data, some organisations to be missed by the query. Turning the order
around resolves this without losing any organisations, tested with DEV and PROD data.
All resources with type `besluit:Bestuurseenheid` also have `org:Organization`
as type. Including both types in the queries leads to some organisations,
specifically municipalities in the `shared` graph, being included twice in the
results. Once with all data and once without label etc. This leads to the
results of both queries being incorrectly combined and having entries in the
final result without label.
