CDB3-347 Registry need to block ability to download docs in lr in case when it belongs to not your objects
Link for example: https://procedure.prozorro.sale/api/registry/lease_requests/602294df571775c6821d402f/documents
Actual result: docs can be downloaded, hovewer ownerToken for object isn't specified
Expected result: docs shouldn't be avaliable for download in that case,cause we even don't know - who is an owner
