Track sets from startgg station/stream automatic tracking updates wrong side after swapping teams

Steps to reproduce:

1. Set scoreboard to track from a startgg station/stream
2. Swap Teams
3. Update score on startgg

Footage: https://www.twitch.tv/videos/2834799111?t=00h52m11s

Outcome: Scores automatically update for the wrong player. In the stream example linked, SwimCheesy was marked as player 1 when the clip started, then was swapped to the player 2 side using the Swap Teams button. After winning game 1, startgg was updated to mark SwimCheesy won the game, but the score was updated in the app (and on stream) for Jeans instead. A moment later, the scoreboard automatically updated the setcount to 1-1, yet startgg was still marked as SwimCheesy being up 1-0 the whole time. I later swapped sides back to see what would happen and the scoreboard showed SwimCheesy being up 2-0 for whatever reason (still 1-0 on startgg).

Reproduce the issue using the listed steps with a startgg station or stream, then inspect the tracking and Swap Teams flow that maps startgg updates to scoreboard players. Compare player identity, side, score, and set-count updates before and after swapping teams; done means updates remain attached to the correct player and match startgg.
