sub-command help display error on multiple alias

[LeeGodSRC]

There is a bug in command system where help display the same arg on help when you have 2 alias in the same sub-command

    @Command({"list", "all"})
    public void list(BukkitCommandContext context) {
        new ArenaListMenu().open(context.getPlayer());
    }

    @Command({"create", "setup"})
    public void create(BukkitCommandContext context, @Arg("name") String name) {

    }
