What was the solution? (How)

The job attachment integ tests don't require a user to be specified, so remove that field from the queues it creates.

What is the impact of this change?

Deadline cloud integ tests should pass

How was this change tested?

Installed into my deadline cloud workspace and ran the integ tests. I ensured they passed.
