Fix crash caused by duplicate peer connections

[sommd]

Sometimes when opening the "Peers" tab on a torrent the app will crash:

For some reason, certain torrents (in bad states I think?) will have multiple connections to the same peer, even multiple connections with the same port:

Not sure exactly why this happens, but removing these duplicates should be a quick fix.
