I'm trying to use https://github.com/cognitect/transit-python and I
created a custom `KeywordField` for this.
The problem is that `transit.transit_types.Keyword` is a callable. Now,
even if I override `_get_default` in `KeywordField`, it still won't work
because
`django.db.backends.base.schema.BaseDatabaseSchemaEditor#effective_default`
checks the value again.
I think a simple fix would be to remove this check from
`effective_default` and immediately make a call where it's necessary
(`datetime.date` etc).
