Video grouping is broken on groups of 1 in vlc 3.2.3

Description

When grouping videos, groups of 1 do not work as they did (and should). When you click on a single video it plays correctly, but you are not able to delete it (the menu is the same as a group's menu and not as a single video's. You also don't see the orange line of the progress you had until now.

Steps to reproduce

1. Have a video which doesn't group
2. Enable grouping
