Metacat

If a resource map has a cito:documents relationship that states that a metadata doc cito:documents itself, that should be ignored in the Solr discovery index. We have metadata documents in the Arctic Data Center that now are indexed as documenting themselves, which causes issues with the "Only results with data" filter in Metacat UI.

Here is an example of a metadata doc that documents itself: https://arcticdata.io/metacat/d1/mn/v2/query/solr/?q=id:%22urn:uuid:dfb9b407-086d-4270-b872-b43504d5e94a%22&fl=id,documents
