Resuming first-stage deployment when doing 2 or more parallell deployments resumes the wrong plan

dep_plan_key = deployment[0]["Key"]

This logic is incorrect when doing multiple parallell deployments in two-stage deployment. If both deployments are prepared, it will fetch the most recent one instead of the correct one, because this just lists the latest deployment instead of the specific deployment that was finished in the first-stage.
