Validate and reset corrupted table filter states

[lkiesow]

Investigating people complaining develop.opencast.org being broken, it seems like there was a change to the filters which cannot handle the previous data which might still be stored in browsers. Like here means, it completely crashes the interface and users just see a blank page.

The error they get is:

Uncaught TypeError: t.find is not a function
    fk tableFilterSelectors.ts:23
    D reselect.mjs:647
    i reselect.mjs:584
    P reselect.mjs:659

This patch introduces a general validation for filters, resetting them if they are corrupted in the sense that the data structure is not correct.

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/opencast-admin-interface:pr-1418

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/opencast-admin-interface:pr-1418

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.
