Django でカスタムユーザモデルを作成しましたが、マイグレーションによるDBのテーブル作成がされません。

前提・実現したいこと

既存プロジェクトにDjangoのカスタムユーザを作成したいと考えています。
以下の記事にしたがって実装することにしました。
Djangoではカスタムユーザを作るべきらしい

ソースコードはほぼコピペで、マイグレーションを実施後、管理者アカウント作成しようとした際に、Userテーブルが存在しないというエラーになってしまいます。
マイグレーションファイルからUserテーブルが生成されて欲しいです。

既存プロジェクトのDBはMySQLを使っています。

発生している問題・エラーメッセージ

$ python manage.py createsuperuser
Username: admin

---中略---

django.db.utils.ProgrammingError: (1146, "Table 'hoge.hoge_project_user' doesn't exist")
