Python scripts run as migrations are preventing newer migrations for model XForm from being applied

[kelvin-muchiri]

Enhancement

Remove implementations of migrations.RunPython from migration file https://github.com/onaio/onadata/blob/main/onadata/apps/logger/migrations/0001_pre-django-3-upgrade.py.

When new fields are added in the XForm model and the migration 001_pre-django-3-upgrade is run for the first time such as when running tests or running migrations for the first time on a new database, the error column X does not exist is raised.

This is because the scripts run within migrations.RunPython are making the presumption that the new field created in a later migration is present in migration 001_pre-django-3-upgrade

One alternative to solve this is to convert migrations.RunPython implementations into Django management commands

Benefits of implementing enhancement

column X does not exist is not raised when applying newer migrations for model XForm
