Migration using ALTER and CREATE/UPDATE in one transaction

See original GitHub issue

Observed behavior

Upgrades are failing for Postgres in case data is updated after schema alterations in this migration:

https://github.com/learningequality/kolibri/blob/30dcfe13713c21c582cfbb8e91fb375f9f13737a/kolibri/core/device/migrations/0005_auto_20191203_0951.py

Failure is Cannot ALTER TABLE device_devicesettings because it has pending trigger events

More info: https://stackoverflow.com/a/12838113

Secondary issue

We have a test environment run on Postgres, but we are not testing our migrations with data, so we cannot know if they actually work. How do we solve this?

Gherkin?

Expected behavior

User can use 0.12, add something to device_devicesettings and upgrade Kolibri afterwards.
