Fix roles getting unselected in ACL tab

[Arnei]

In the access policy tab, when adding new roles, old roles would be removed. Basically, changing the roles in some manner would result in wonky behaviour.

This patch fixes that, mostly by reverting 9d0a7b2 and making sure the policy key id is more reliable than index.

How to test

Can be tested as is, with any event. Make sure that #1523 is still fixed as well.

Use docker or podman to test this pull request locally.

Run test server using develop.opencast.org as backend:

podman run --rm -it -p 127.0.0.1:3000:3000 ghcr.io/opencast/admin-interface:pr-1576

Specify a different backend like stable.opencast.org:

podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ghcr.io/opencast/admin-interface:pr-1576

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.
For more options you can pass on to the proxy, take a look at the README.md.

Thanks @Arnei,

I can confirm that the changes work as expected. However, the Access Policy tab currently has a noticeable delay. Click-Actions are applied only after about 1-2 seconds at best, and I also encountered a white page after adding more than three roles with several action (checkbox) changes.

My suggestion would be to move the inline functions into static methods, although I'm not sure whether that would fully resolve the issue.

The Access Policy tab seems to have the issues you noticed also on r/19.x I think. Could you confirm?

[ferishili]

Could you confirm?

Yes, I can confirm that as well, but it seems to me as it works just a little bit smoother!
