Description
When removing field of base class model in my migration and than using RunPython with subclass model query I face exception django.db.utils.OperationalError: (1054, "Unknown column 'bugapp_person.name' in 'field list'"). It looks like during migrating, current migration state of submodel does not reflect field removal. Base class is alright though. Additionally, this happens only when at least one extra model with OTO field to base model exists.
This occurs in Django 1.8. I had no problem with any of 1.7.x version, last tested was 1.7.7. Simplified snippet attached below runs smoothly with version 1.7 and should reproduce the error in 1.8.
