App no longer detects local unsynced changes in its data directory.

### ⚠️ Before posting ⚠️

- [x] This is a **bug**, not a question or an enhancement.
- [x] I've [searched for similar issues](https://github.com/nextcloud/android/issues) and didn't find a duplicate.
- [x] I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
- [x] I agree to follow Nextcloud's [Code of Conduct](https://nextcloud.com/contribute/code-of-conduct/).

### Steps to reproduce

1. Download (sync) a text file in the app.
2. Make a change to it in your preferred app (i.e. ViM running under Termux).
3. Open Nextcloud app and refresh the folder containing the file.

### Expected behaviour

In the past, this would have changed the icon from a green check mark to a red X, at which point the user could sync the file again, and thus upload their changes manually.

### Actual behaviour

Now, not only are my modified files not being seen as modified, but new files aren't seen at all in the app. And, if I tap the file and select 'sync', instead of uploading my changes it redownloads them overwriting my changes!!!

### Additional information

Currently I'm trying to use this to sync notes in a note taking app. Thankfully I didn't write much before finding out sync overwrites newer files...

Part of me thinks this may not be a bug, but actually intended behavior - yet that also seems silly since this is objectively worse functionality.
