cli createAdminUser register AdminUserService twice

[blue-hope]

when use cli - createAdminUser, AdminUserService is registered(or injected) twice.
In constructor of adminUserService,

constructor(connection, entityManager) {
      this.connection = connection;
      this.entityManager = entityManager;
      connection.subscribers.push(this);
      console.log('registered')
  }

I made logger like above, and it is printed twice

because the AdminUserService is registered twice, subscribers are registered twice and finally beforeInsert is called twice

I don't know why this happened. Because of the above issue, hashPassword is called twice.
