Dummy player scores not in Tab List

Giving scores to dummy players and attempting to display them in the tab list fails to work.

Steps to Reproduce:
1. Create an objective, any will do, and display it in "list" (tab list)
2. Give yourself a score on said objective. You should see that when you press tab
3. Give a dummy player a score on said objective. It does not show up.
4. Neither the dummy player's name or score show up
