Fix potential race in _start_key_lookups
If the verify_request.deferred has already completed, then `remove_deferreds` will be called immediately. It therefore might resolve the server_to_deferred deferred while there are still other requests for that server in flight. To avoid that, we should build the complete list of requests, and *then* add the callbacks.
