### Bug description

When a folder is deleted via the Nextcloud web interface, the Windows Desktop Client detects that the folder was removed from the server, but fails to remove the corresponding local Virtual Files folder.

Nextcloud reports:
"Temporary error when removing a local item that was removed from the server."

Windows Explorer also fails to delete the remaining local folder with:
"Error 0x80070091: The directory is not empty."

However, the same local folder can be deleted successfully using PowerShell:

Remove-Item -LiteralPath "C:\Nextcloud\test_folder" -Recurse -Force

PowerShell completes without any error.

Immediately afterwards, Nextcloud Desktop reports "Everything is synced!".

Server: Nextcloud 31.0.14 Enterprise (IONOS)
Desktop Client: 34.0.2
OS: Windows 11
Virtual Files: Enabled

### Steps to reproduce

1. Synchronize a folder with Nextcloud Desktop using Virtual Files.
2. Delete the folder via the Nextcloud web interface.
3. Wait for the Windows Desktop Client to synchronize the deletion.
4. Nextcloud detects that the folder was removed from the server, but fails to remove the local folder.
5. Try to delete the remaining local folder using Windows Explorer.
6. Windows Explorer reports error 0x80070091: "The directory is not empty."
7. Delete the same folder using PowerShell with Remove-Item -Recurse -Force.
8. The folder is deleted successfully and Nextcloud immediately reports "Everything is synced!".

### Expected behavior

When a folder is deleted on the server, Nextcloud Desktop should automatically remove the corresponding local Virtual Files folder without requiring manual deletion via PowerShell.
