Auto-Automatch players no longer insist on being the host.

Tiny change, but I think it's a big enough deal to include in this release.

For the sake of the users who don't currently use or understand automatch, I originally planned auto-automatch to just bring your matched opponent to your game. But that doesn't always work with because of the 50-person lobbies, so instead I made it send both players to Outpost anyway.

Since I'm already doing that, I might as well remove the restriction that auto-auto only creates matches where you (the auto-auto user) are the host. That way two auto-auto users can match each other, and a match between an auto-auto and regular automatch user doesn't have to settle for having the auto-auto user as host if the opponent has more cards.

So I think it'll generate more matches and improve their quality. I haven't been testing with this, but it's such a small change that I'm not very worried.
