[Bug]: [f2v] Spaces are double encoded in directory and filenames

[max-nextcloud]

⚠️ 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 OR Nextcloud Community Forum (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

Filenames and foldernames with spaces are shown with %20 instead:

Folder creation seems to work fine but on a reload they are also shown with %20.

Steps to reproduce

1. Run the current master branch
2. Go to apps/files and create a folder and upload a file with spaces in the name
3. Reload the page
4. See the %20 like on the screenshot

Expected behavior

Properly handle spaces inside file and folder names - i.e. display them as a simple space.
