Query on facets should update the count values of all facets
Currently, if you do an item-search on e.g. "Gephi" and then choose a facet to filter the result e.g. on the activity "Modeling" (api/item-search?q=Gephi&f.activity=Modeling), the returned count-values for the facets are not updated. They still show the results for the q-search (means, they still show the results for api/item-search?q=Gephi - you can also have a look on the frontend: https://sshoc-marketplace.acdh-dev.oeaw.ac.at/search?facets=%7B%22activity%22%3A%5B%22Modeling%22%5D%7D&query=gephi vs. https://sshoc-marketplace.acdh-dev.oeaw.ac.at/search?query=gephi shows different count in search results but no change in the counts of the facets).
Expected behaviour: When using facets to filter the result then the count of all others facets should be updated based on this filter (e.g. in our example the filter on "Modeling" should deliver back for e.g. types the result "Tool (2), Paper (0), Software (0), Tutorial (0)".
