[BFComms] Additional Matchmaking Backend Changes

We have now made additional changes to the matchmaking update we performed last week. This should improve the situation where players experienced an excess of bots in their lobbies when enough players are queuing for matches. Please keep in mind that limiting your matchmaking searches to only a few maps and modes might prevent you from experiencing persistent lobbies if your choices are too limited. We'll keep you posted as we make progress. Thanks for your feedback after the changes, it's been very helpful!
