Asure sync between query-schedule and result

[achaikou]

Real case scenario from failing integration test:

Client fails with
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: http://server:8080/result/5e66997e-8b8d-4647-b43c-1bbae77dd54c/stream
because this runs earlier than this (or something nearby) is run.
Can be reproduced by manually adding timeout before operation in Schedule.
