[CLIENT] Can't Invite More Than 5 People To Custom Game Lobby

When setting up a tournament draft, only 5 players total could be on any team (From what I've seen spectators don't count towards this total). Once 5 players are present, the option to invite a player was grayed out. A workaround is to invite all players and have them accept at the same time.

1. Create custom game.
2. Invite 4 other people.
3. Once the 4 people accept, try to invite more people.
