"Logged out" page is showing when re-visiting the instance

[kulmann]

Describe the bug

When I re-visit my oCIS instance after a longer time it greets me with the Logged out page being shown.

Steps to reproduce

1. Login in to oCIS
2. Close the browser and grab a coffee
3. Open the browser and re-visit oCIS

Expected behavior

Getting greeted by the login page.

Actual behavior

Getting greeted by the "logged out" page.

Additional context

While technically correct (my old access token in the localStorage has in fact expired in the meantime), the UX is awful. When the access token has expired for a longer period of time (basically anything more than a few seconds), the expectation is to just get to a login page. Seeing the "logged out" page is useless information and having to click on login again is just one extra-click.

@tbsbdr thinking about making this a p2 because it's really annoying... what do you think?
