Automatic Upload only works with default Folders (Android 16)

### ⚠️ Before posting ⚠️

### Steps to reproduce

1. create a custom folder "photos"
2. set the camera path to sync photos to this folder

RESULT: Nothing gets synced.

- Nextcloud HAS full access to ALL files.
- Manually Sharing a photo/file and selecting the folder configured for automatic sync works instantly!

### Expected behaviour

This should work.

### Actual behaviour

What seems to happen instead is that nextcloud wants to shove everything under SofortUpload/[App/Folder]. I.e. if you activate automatic upload for WhatsApp Images and you DO NOT change the path the App will create

"./SofortUpload/WhatsApp Images"

! Then files are uploaded immediately !

Changing the path breaks uploads for WhatsApp images.

Even worse, if you disable the sync and remove "./SofortUpload/WhatsApp Images" and then reactivate the sync nextcloud will not create the folder again. Manualle creating "./SofortUpload/WhatsApp Images" does not help. You cannot sync this stuff again, ever.
