Do not ask password in createsuperuser command if used custom user model without password field

[Semyon Pupkov]

In a case when user model customized as:

from django.contrib.auth.base_user import AbstractBaseUser

class UserManager(BaseUserManager):
    def _create_user(self, portal_user_id, email, **extra_fields):
        del extra_fields['password'] <<-- trick to fix errror

        email = self.normalize_email(email)
        user = self.model(portal_user_id=portal_user_id, email=email, **extra_fields)
        user.save(using=self._db)
        return user

    def create_superuser(self, portal_user_id, email=None, **extra_fields):
        return self._create_user(portal_user_id, email, **extra_fields)


class User(AbstractBaseUser):
    password = None
    last_login = None
    
    objects = UserManager()
    ...

command ./manage.py createsuperuser --email=me@… should not ask password if settings.AUTH_USER_MODEL does not have a password
command ./manage.py createsuperuser --email=me@… --noinput should not pass a password to create_superuser method
