test: Add failing test case for unnecessary delay for end-judging voting

If all of the players that submitted answers have also all completed
judging, then there's nobody left to wait for and it's pointless to
wait for the idle timer to fire and to force everyone to vote to end
judging. Yet, that's what the implementation currently does.

This commit adds a new test case, which fails, showing the point at
which the game should automatically advance to scoring, (once every
player who submitted an answer has also voted).
