Do not include dynamically loaded values into OVO testing

Those OVO values loaded dynamically (for example [1]) should not be
added to the tested object. A dynamic column in a DB register is a
``sqlalchemy.orm.AppenderQuery`` object that represents the needed
query to retrieve this value.

These OVO fields, mapped from the DB object, should be considered as
synthetic fields and not be included in
``_BaseObjectTestCase.obj_fields``.
