Auto Upload does not work if the destination folder is not InstantUpload

### ⚠️ 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

Go to Settings, Auto upload, find folder to auto upload, click the non-descriptive cloud icon to, upload starts normally.

Now tap the 3 dots menu, change the "Remote folder" to anything except the "InstantUploads" folder... upload *never* starts.

Reset back to InstantUploads, and it start working again.

### Expected behaviour

Uploading starts (just like it does for InstantUploads folder)

### Actual behaviour

Upload never starts. Nver.

Have tried:
1. Waiting
2. Force closing app, restarting
3. Clear cache in between force closing and restarting

This is not a space, network, or android settings issue as whenever I rest to "InstantUploads" it starts working again.

This is quite a longstanding bug that ... that just completely invalidates the usage of Nextcloud...

Please see this with priority.

### Additional information

Look for the Duas folder in the logcat

Start with the linked Android logcat and search for the Duas folder and auto-upload handling when the remote folder is not InstantUploads. Reproduce the issue using the Auto upload settings and a different remote folder; done means the upload starts and behaves as expected for non-InstantUploads destinations.
