### Steps to reproduce

Manually upload a file from gallery to a specific directory on Nextcloud.
After the upload is completed multiple copies were saved locally on the device in following paths:

- internalstorage/Android/media/com.nextcloud.client/nextcloud/user@nextcloud.server.domain/filepath mapping to server
- internalstorage/Android/media/com.nextcloud.client/nextcloud/tmp/user@nextcloud.server.domain/filepath mapping to server

e.g.:
* Document is: `IMG20250110_10000.jpg`
* Server: `nextcloud.example.com:443`
* Server Path for upload: `Photos/S21Plus/2025/01/IMG20250110_10000.jpg`
Files are duplicated across following paths:
- `internalstorage/Android/media/com.nextcloud.client/nextcloud/user@nextcloud.example.com%3A443/Photos/S21Plus/2025/01/IMG20250110_10000.jpg`
- `internalstorage/Android/media/com.nextcloud.client/nextcloud/tmp/user@nextcloud.example.com%3A443/Photos/S21Plus/2025/01/IMG20250110_10000.jpg`

### Expected behaviour

Files should not be duplicated multiples times on the device.
Only keep original file locally.

### Actual behaviour

Files getting duplicated multiple times locally, leading to device running out of storage.
While failing to upload further files due to lack of local storage.
