While running

message.guild.members.unban(client.users.fetch(config.admin.owner.id), "reason")
// Ignore the config part it's fine

Turns out, you should just unban the people by their IDs instead of their user property. So, to unban the banned member use this code instead:

constDiscord = require('discord.js');
const client = newDiscord.Client();

const embed = newDiscord.MessageEmbed()
.setColor('#39de33')

module.exports = {
  name: 'unban',
  description: "This unbans a user",
  execute(message, args){
      if (message.member.permissions.has("BAN_MEMBERS")){
          if (!isNaN(args[0])) {
            const bannedMember = message.guild.members.cache.get(args[0]) // Get the `member` property instead to recall later.var reason = args.slice(1).join(" ");
            if(!reason) {
              reason = "No reason given!"
            }
            if (bannedMember) {
              bannedMember
                message.guild.members.unban(bannedMember.id, reason)
                .then(() => {
                  embed.setDescription(`Successfully unbanned **${bannedMember.user.tag}**`); // `user` is undefined.
                  message.channel.send(embed);
                })
                .catch(err => {
                  embed.setDescription('I was unable to unban the member');
                  message.channel.send(embed);
                  console.error(err);
                });
            } else {
              embed.setDescription("That user isn't in this guild!");
              message.channel.send(embed);
            }
          } else {
            embed.setDescription("You need to provide an user ID to unban");
            message.channel.send(embed);
          }
      } else {
        embed.setDescription("You do not have `BAN_MEMBERS` permissions to unban this member");
        message.channel.send(embed);
      }
  }
