Comment (by Sanskar Jaiswal):
Upon doing some more debugging, I found some peculiar behaviour. I tried
to print `generated_operations` at the end of the function
`generate_deleted_models's `. This is the output: `{'some':
[<RemoveField model_name='book', name='authors_book'>, <DeleteModel
name='Book'>, <RemoveField model_name='pub', name='authors_pub'>,
<DeleteModel name='Pub'>]}`.
The method is adding four operations to the `generated_operations`, but
only three of them show up in the actual migrations file. Am I missing
something here?
