fixed login routing issue causing onboarding to not be shown
If the users credentials are removed for whatever reason, set the user to logged out
Merge pull request #19 from hatched/fix-login-redirect

To QA:
Sandbox:
Make sure you are able to log in/out. (u: admin p: admin)
Make sure the onboarding can be displayed at the root url. To clear your localstorage, open up the app and type `localStorage.clear()` in the console, then refresh, it should show the onboarding.

Real Env:
Make sure you are able to log in/out (password is in your environments.yaml file)
