The last parameter of change_column_null only affects existing records, thus the default still needs to be set in another migration.

@justin808 Ready for review. |

Why 2 migrations?
Does change_column_null handle migrating old records? We might need a couple lines of SQL to update the existing records. Then again, there probably aren't any, or else the UI would have crashed.

Well, yes, that last parameter (empty string) of change_column_null replaces null values of existing records, so we don't need SQL statements here.
But it still doesn't set the column's default for new records, thus we do need a second migration to change_column_default.
