[Bug]:Files root folder for external data not possible

[SprotteCode]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

After I have updated Nextcloud Server from Version 23 to version 24.05, my external root folder is not longer accessible. In version 23 I had to use "" in the folder name of the external files and had access to my external data via SMB/CIFS. Now I have to give the folder a name, which let's me not access it as root folder.

Steps to reproduce

1. Go to Options (Einstellungen)
2. Access external files (Externe Dateien)
3. Connect via SMB/CIFS to an external drive and let the folder name be ""
4. Can't access the folder in files menu any longer

Expected behavior

Using the "" should cause the external files to be seen as root folder
