 From what I understand, `makemigrations` produces migrations for unmanaged
 models, and the state of those migrations are tracked, but no SQL is
 actually run.

 The way that `makemigrations` handles circular `ForeignKey` references
 between two models is to produce two migrations. (This may only happen if
 the two models are in different applications.)

 However, when both the models involved are unmanaged (`managed = False`),
 the second migration is not produced, leaving the migrations overall
 inconsistent with the models (and therefore, useless).

 The workaround appears to be temporarily removing the managed flag,
 running the migrations, restoring the managed flag on the models and
 manually inserting it into the migrations.
