Menu Separators sometimes broken in the pause Menu

[salomj]

Steps to reproduce

1. Add two or more separators to the default-config.json for a mod
2. Verify that is works on the title screen mod menu
3. Start the game, and try to open the pause mod menu

Don't worry, this is my fault, so I'll take this one., and thankfully separators are also not listed anywhere in the documentation, so that is good as well.

Looks like the issue is that in UnityEngine.Object.GetName(this) this is null.

Looks like it might be a cleanup issue, as it seems that multiple items in the Separators list have Element == null.
