Add back muted icon into post-game lobby

Although I do think that the new feedback icons in post-game (the report, honour friend buttons) are snazzy, I noticed there's no longer an icon showing that you muted someone over the honour button. This was very important as, if you muted someone early game for being particularly toxic, it's often hard to remember to report them by the time you hit late game, especially since you've stopped seeing their toxic BS for the entire game.
