When going back in the onboarding flow we end into a loading animation that never ends

[TimoPtr]

Description of problem, include YAML if issue is related to notifications: If a user open the app and start the onboarding flow and press back he ends up into a screen with a loading indicator and nothing else will happen. We should handle this case and close the activity once we reach this step.
