Preview image not shown in user settings

[sanchosk]

Describe the bug
I did initial run of the recognition for faces. All went well, I have multiple hits, but all the preview images in user settings page for Recognize are empty.
The URL starts with /index.php/code/preview?... As my nextcloud installation is in folder /nextcloud, the previews do not work.

To Reproduce
Steps to reproduce the behavior:

1. Install Nextcloud 24.0.4
2. run the php script from server shell to recognize faces (occ recognize:classify-images)
3. open the settings page of a user, navigate to the Recognize page
4. Observe multiple tags, all detected as People Untitled, but all images having only broken link placeholder

Expected behavior
I expected the preview images to be shown. If I inspect the element and modify the tag and add /nextcloud to the URL, the image is shown OK.
