[Co-op] Replays with only one player with prestige

When only one player is using a prestige and the other is playing with the standard loadout, the prestige indicator will eventually be duplicated in the replay.

Upon initially loading the replay, the indicator will only appear once, as expected. When changing the camera to the other player, the indicator will be duplicated for the rest of the replay.

This appears to be a minor, visual-only bug that does not interfere with the playback of the replay.
