Fix redirect if a user is locked out

[Elblinator]

Describe the bug
Sometimes a user is not correctly redirected if they are locked out of a meeting

How to Reproduce

1. Have a user (B) in several meetings (uncertain if that is a requirement but it is far more likely to happen with several meetings)
2. With one browser login as user B
3. Navigate to any page (except the autopilot)
4. Make a reload/Make a hard reload
5. With another browser login as an admin and lock out B
6. The page "You are not supposed to be here." is shown instead of the wanted redirect
7. IF you do a normal reload in the home then the content in the mat-card and the menu left vanishes and you need to reload to be able to navigate somewhere else

Expected behavior
B should immediately be redirected

Your issue description mixes user A and user B. I fixed it.
