Show correct amount in "Receive motions from" and "Forward motions to"

[Elblinator]

context:
OpenSlides/openslides-autoupdate-service#1216
FOR TESTING NEEDED: OpenSlides/openslides-autoupdate-service#1365

Current behavior
(correct) list view

detail view:
from committee admin

from superadmin:

Edit view:
from committee admin:

superadmin:

Wanted behavior

• in the detail view: the complete list from "forward motions to" and "Receive motions to" should be shown
• in the edit view:
  the committee admin should see every meeting which they can see/get from the autoupdate.
  There are two cases in which the committee admin can see a committee

1. the committee admin is directly or indirectly the committee admin from the committee
2. the committee can already forward to this committee while the committee admin is not committee admin from that committee

Case A should always be not diabled (currently the case)
Case B should be disabled (that is missing)

The payload to the backend should not deviate from the current payload.
Even though the committees are not shown to a committee admin they are being send to the backend. If they are not send the backend returns an (correct) Error message.

This seems like a larger issue. I am not sure how to handle it.
Say you a committee admin is logged in. How does the client know, if a committee should be checked-disabled? What should the client send to the ba in this case?

I updated the description

Here the steps how to reproduce it are missing.

[reiterl]

I can reproduce it, with following steps:

1. create a committee 1, a committee 2 and a user A
2. set to committee 1 that it can forward/receive from committee 2
3. set user A as committee manager of committee 2
4. login as user A and go to the detail view of committee 2

Here you won't see any committee with received/forward, but in the committee list, you see there are such committees,

[reiterl]

The autoupdate service doesn't provide a committee (and its name), if a user doesn't have access to it.
A user has access to a committee iff they is orga admin or in the committee or committee manager of it.
