Onboarding passes with reset atSign

[pcutillas]

Which at_widget package you find issue with?

at_onboarding_flutter

On what platforms did you experience the issue?

Android

What version are you using?

6.1.11

What happened?

I was previously signed in on a device using an atSign, and after resetting the atSign and restarting the app, I'd expect onboarding to return AtOnboardingResultStatus.error, but it returns AtOnboardingResultStatus.success.

Steps to reproduce

1. Onboard new or activated atSign with `AtOnboarding.onboard()`
2. Reset atSign through the atSign portal
3. Close and restart app
4. Onboard the same atSign with `final result = AtOnboarding.onboard()`, setting `atsign: await _keyChainManager.getAtSign()`
5. Inspect the result status

Actually, this happens even without passing the atsign to the onborading function in step 4
