Bot pairing vs itself

Seems like there's a bug in the TwinDuel rankings: [1]

DuoLedByDroid and TwintelligenceTeam each have battles vs themselves and it's counting as an extra pairing. (I noticed because the archived rankings code determines that rankings are stable by everyone having the same number of pairings.)

Same for PanzerGeneral in minimelee: [1]

OK, I modified the code that checks that pairings are still in the rumble to also check against the bot name. They should be fixed next time they get a result upload.
