The LastUpdateTime is no longer updated on every resync. It only changes if the underlying status has changed, so that it effectively shows when the transition happened.
This change happened in ab750f48aa002504a18602e29f18af561b52cfe0, but we missed this test. It only fails when it has been more than ten minutes since the CredentialIssuer transitioned into a healthy state, but that can happen in our long-running CI environments.
