Login loop after logout

[Elblinator]

Current behaviour:
If you logged out and try to login again, then you are stuck in a loading loop for

Reproduction:

1. Login as any person
2. log out
3. log in with the same account
4. there is a spinning login button
5. reload the page and you are logged in

Wanted behaviour:
The indefinitely long spinning time should be prevented

The error does not seem to be related to the login issue

This seems to be related to the operator not getting ready. There were already issues regarding this kind of issue (e.g. #1609, #1390).
After fixing that we might also want to add an integration test for this.

This seems to be a race condition within autoupdate-stream.ts.

On logout the client sends the following messages to the shared worker:

1. Individual subscription closes
2. Endpoint update
3. Auth change

It seems that subscriptions do not get correctly closed if the set endpoint or auth change message (not exactly sure which one, maybe both) get sent before the close message was sent.
The results in a broken subscription that does not contain data within its stream.

I cannot replicate this anymore.

Problem is solved.
