theming app not working after update from 12.0.6 to 13.0.1

[profhccaesar]

Steps to reproduce

1. Update Nextcloud from 12.0.6 to 13.0.1 ("stable" update channel)
2. Now the login screen background, title bar and folder icons appears in an ugly brown color
3. Login as admin, go to settings -> theming and change the color
4. Folder icons uses now that color, but the login screen background and title bar still use that brown color
5. Go to settings -> theming again and upload a background image
6. Logout
7. The background image is not used

Expected behaviour

Setting a color in the theming app should change the background and title bar color as well as folder icon color.
Uploaded background image should be used on the login screen.

Actual behaviour

Setting a color in the theming app changes only the color of the folder icons, nothing else.
Setting a background image has no effect.

@profhccaesar Is this still an issue with 13.0.2?
