### ⚠️ Before posting ⚠️

- [X] I've [searched for similar issues](https://github.com/nextcloud/android/issues) and didn't find a duplicate.

### Steps to reproduce

1. Install Nextcloud app.
2. Connect to a server.
3. Configure a folder for autoupload.

### Expected behaviour

Files should start uploading, disabling the autoupload folder and/or cancelling the uploads (via the X in the upload menu) should cancel the pending uploads.

### Actual behaviour

X in the uploads menu does not clear the pending uploads, nor does disabling the autoupload folder. Force closing the app also doesn't cancel them (they are still there on app reopen). No way to stop the upoads anymore!
