Designate DNS – list zone exports API, filtering results.

According the documentation regarding "list zone exports API":
https://docs.openstack.org/api-ref/dns/?expanded=list-recordsets-in-a-zone-detail,list-all-recordsets-owned-by-project-detail,create-zone-detail,list-all-zone-exports-detail#list-all-zone-exports
it applies filtering listed exports, for example by status, but actually it doesn’t seem to be work.

Tempest test to run the scenario is available here (see patchset1): https://review.opendev.org/c/openstack/designate-tempest-plugin/+/785780

“test_list_zone_exports_filter_results” test fails with:
