Return 404 for non-existing Logistics Objects instead of 403 (authz scenario)

When an authenticated client requests a logistics object that does not exist, the NE:ONE server checks the ACL and returns a 403 "Forbidden" instead of "404 Not Found".

NE:ONE Server should check if a requested logistics object exists. If the logistics object exists: Check ACL and return "200 OK" or "403 Forbidden". Otherwise: return 404 "Not Found".
