When `models.FileField` is in `models.Model`, everything works as
expected.
When `models.FileField` is in `models.Field` which is in `models.Model`,
when saving, `ProgrammingError` `can't adapt type 'TemporaryUploadedFile'`
is raised.
That happens, because `FileField.save_form_data()` makes `FileField` to
hold `FieldFile`, but `models.Field` makes its `FileField` to hold
`TemporaryUploadedFile`.
I've prepared repo with minimal setup to reproduce bug:
