### Bug description

Temporary files (starting with special character) breaks file sinchronization on Windows client app when VFS is enabled

This issue appears to be related to [#4410
](https://github.com/nextcloud/desktop/issues/4410) and https://github.com/nextcloud/desktop/issues/4246

### Steps to reproduce

Steps to reproduce the behavior:
1. Enable VFS and have Nextcloud syncing your local directories
2. Trigger the creation of temporary files on one of those folders. For example open an Excel file and start editing it
3. Edit the file but don't save it, to trigger the temporary file creation
4. The Nextcloud app will stop synchronizing files and from now only displays "Checking for folder changes"

### Expected behavior

A temporary file should not break file synchronization.
