### Bug description

Folders deleted on a Windows endpoint are only deleted locally, but never on the NC server as long as E2EE is activated in the Desktop Client.

It is for sure a leftover from https://github.com/nextcloud/desktop/issues/5564 where all that mess started.

Once E2EE is disabled (in the Desktop client itself), all previous performed deletions are performed instantly, so the "folder deletion queue" is being emptied. On the server they are removed, also the activity app confirms this.

### Steps to reproduce

1. Enable E2EE (install app, activate on the Desktop client)
2. Create a folder (no matter if done on the web, another endpoint like iOS/Android client or the same Desktop Client, also doesn't matter if inside or outside an E2EE folder - right, **it also affects folders outside of E2EE folders!**)
3. Make sure the created folder exists on the server, maybe additonally check activity app
4. Delete a folder on the endpoint with Desktop client

### Expected behavior

The folder is deleted locally and on the server.

### Additional info

- https://github.com/nextcloud/desktop/issues/5564
- Deletion of folders using other endpoints (the web interface, iOS client, Android client, ...) works without any issue, instantly.
- Creation, renaming and moving folders is synced fine. It's "just" that deletion... which produces very very VERY **confusing inconsinstent states** over time, depending on the usage of NC very quickly.
- Additionally (probably a 2nd issue or a variant of this one): folders INSIDE an E2EE folder which are deleted (e. g. using the iOS client), are not deleted on the Desktop client endpoint. E2EE is just a complete mess... 🙄🙄🙄
