ci: on test update the error message

[nabim777]

Description

There is a flaky CI failure during user cleanup in the API tests. The current error messages do not provide enough information to help with debugging.

The failure did not occur while working on this PR, so the root cause could not be identified. This PR adds error messages to make it easier to identify the issue when the flaky failure happens again.
