scenario (fix): adjust for change to engine SubmissionResult types

This isn’t a great sign about the engine-side change. I’m going ahead with it to get this into review quickly, unblocking both the Central integration and my ability to get back to reviewing other work in flight.

I think it’s okay to just remove this parameter for now, because there won’t be tests exercising chunked submissions until we support `<upload>` and submission attachments.
