4 player challenges can still play 2 player games

See challenge 1174 for an example.

Most of the games are played only between the issuer and tscommander-ml.

In this case I believe it is because tsadmiral and tscaptain have is_gpu_enabled turned on. So they only play if the challenge happens to be selected to play on a gpu enabled server.

I believe it's also the case that if one of the challenged bots had a failed upload or was otherwise disabled the remaining two challenged bots would continue playing 2 player games against the issuer.

@lidavidm I thought we paused the whole challenge if any player's bot was disabled?

[lidavidm]

If the initiator's bot is disabled, yes, otherwise it will keep trying to play games. I guess we should probably make sure all bots are at least able to play a match before we issue one.

[julskast]

yes @lidavidm I think that makes more sense
