Cannot use facetGroup conjunction/disjunction/negation on non managed referenced groups

[novoj]

This query which targets tags reference which si grouped by tagCategory which itself is not managed by evitaDB, cannot be switched to conjunction behavior for tags:

{
  queryProduct(
    filterBy: {
      entityLocaleEquals: cs
      userFilter: [
        {
          facetTagsHaving: [
            {
              entityHaving: {
                attributeCodeInSet: [
                  "new"
                ]
              }
            }
          ]
        }
      ]
    },
    require: {
      facetTagsGroupsConjunction: {
        filterBy: {
          
        }
      }
    }
  ) {
    extraResults {
      facetSummary {
        tags {
          count
          groupEntity {
            type
            primaryKey
          }
          facetStatistics(
            filterBy: 
            { attributeIsVisibleInFilterEquals: true }  
          ) {
            requested
            count
            impact {
              difference
              matchCount
              hasSense
            }
            facetEntity {
              primaryKey
              type
              attributes {
                name
                code
              }
            }
          }
        }
      }
    }
  }
}

We should also support filtering selecting tagCategory by primary keys even if it's not managed by evitaDB and there is no index for it. We could take the data from the facet index of the reference.
