[IMP] fields: infer required=True on related fields
One can infer related=True on a non-stored related field if all fields on the path are related. This cannot be done if the related field is stored: when you create a record, the database row is created first, and the related field is computed and stored afterwards. Making the field required in that case would trigger a non-null constraint violation.
