fix: Reactivate User test flake

[johnkim-det]

Ticket

Description

Potential fix for flaky 'Deactivate and Reactivate' test.

Not reproducing failures locally, doesn't seem like this would need to be handled differently for CI. Trying out adding a validation step used in a similar test that's missing here, even though I'm not sure why that would lead to sign out timing out.
