[Pulp-list] 3.3.1 migration error

[Tatiana Tereshchenko]

Dennis,
FWIW, I believe there are a couple of problems here but neither of them is
related to your advice to manually modify a migration.
Problem #1.  `django-admin makemigrations` was run, so this 0009_auto_...
migration got created. I think the installer doesn't run this command, or
does it?
Problem #2. The migration 0008 was not in sync with the model, so
makemigraitons will create a new migraiton if run. Fixed in 3.3.1.
