Error when running /party leave as leader.

[TheDeafCreeper]

You do still leave the party (you probably shouldn't), but an error does also occur.

This is interesting. The ability to leave your own party as leader is intended. When that happens a random member will be promoted to leader.

But seeing as you were the leader, AND the last player to leave, that must've been what caused this. I'll mess around and see what I can do to adjust this
