    Lazy-load instance attributes with read_deleted=yes

    If we're doing a lazy-load of a generic attribute on instance, we
    should be using read_deleted=yes. Otherwise we just fail in the load
    process which is confusing and not helpful to a cleanup routine that
    needs to handle the deleted instance. This makes us load those things
    with read_deleted=yes.
