Last 10 games performance doesn't take races into account for 1vs1

For example, looking at RichApm#2386 during season 3: his best ladder placement was 6646 RP with Human, yet his performance is still based off games he played with different races. Either place the performance somewhere outside of the highlighted 1vs1 box (Diamond 3 with Human), or only take into account games with the race associated to that rank (in this case, "W-LLL-WW-L-W-LL" instead of the current "L-WW-LLL-WWW-L")
