Salman Ahmed f82ed64aa7 Fix participant panel null user test no longer functioning properly
I guess the changes that involved `MultiplayerTestScene` having a test
user lookup cache caused this test case to false-pass silently.

Added an explicit assert which ensures the added user indeed has a null
`User` value.
