Having custom user model creates migrations in django.contrib.auth

[Vidir Valberg Gudmundsson]

This happened when reporting #22853, so it has the same custom user model and same occurences.

Models

from django.db import models
from django.contrib.auth.models import AbstractUser


class Profile(AbstractUser):
    title = models.CharField(max_length=255)

Makemigrations output

$ ./manage.py makemigrations
Migrations for 'testapp':
  0001_initial.py:
    - Create model Profile
Migrations for 'auth':
  0002_auto_20140617_1231.py:
    - Remove field groups from user
    - Remove field user_permissions from user
    - Delete model User

New auth migration content

class Migration(migrations.Migration):

    dependencies = [
        ('auth', '0001_initial'),
    ]

    operations = [
        migrations.RemoveField(
            model_name='user',
            name='groups',
        ),
        migrations.RemoveField(
            model_name='user',
            name='user_permissions',
        ),
        migrations.DeleteModel(
            name='User',
        ),
    ]

Consolidating this with #22853.
