fix: Deactivate User test flake

[johnkim-det]

Ticket

Description

Potential fix for flaky "Deactivate and Reactive" test.

Not reproducing failures locally, doesn't seem like this would need to be handled differently for CI. Attempting to add some assertions that are used in the similar "Bad Credentials" test, which is not flaky on CI, to see if that addresses the issue.
