Comment (by Paweł Kotiuk):
I have simpler reproduction for you using postGIS this time:
1. Download repro_project.zip I uploaded and unpack it.
2. Launch postgis using docker `docker run --rm -it -e
POSTGRES_PASSWORD=password -p 5432:5432 postgis/postgis`
3. Open terminal and launch commands `./manage.py makemigrations` and
`./manage.py test` -> everything is fine
3. Change dim from 2 to 3 in the `models.py`
4. launch commands `./manage.py makemigrations` and `./manage.py test` ->
you get error: `django.db.utils.DataError: Column has Z dimension but
geometry does not`
