In compute-hcls-stats issue if multi distributions have same accessURL

[vemonet]

In compute-hcls-stats if multiple RDF distributions (void:Dataset) have the same accessURL (graph), we will add the new stats to all of those distributions

When we add a new version we need to make sure that all triples accessURL pointing to the graph URL has been deleted

DELETE
{   ?datasetMetadata dcat:accessURL <?_inputGraph> }
WHERE
 { 
  ?datasetMetadata dcat:accessURL <?_inputGraph> .
 }

There should be only one access URL by graph

Use this script to remove all accessURL: https://github.com/MaastrichtU-IDS/data2services-insert/blob/master/insert-biolink/delete-metadata-accessURL.rq
