> Adding a prefetch to a selectQuery via the relationship's name only doesn't seem to work.
> Entity "SMReceipt" has a to-one relationship "shop" to the entity "SMShop". The first
fetch performs a prefetch as expceted, the second fetch performs no prefetching.

> FETCH 1 (working)
> ----------------------------------
> SelectQuery<DataRow> q = SelectQuery.dataRowQuery( SMReceipt.class );
> q.addPrefetch( SMReceipt.SHOP.joint() );
> List<DataRow> list = objectContext.select( q );
> ----------------------------------
> GENERATED SQL
> ----------------------------------
> SELECT t0.creation_date, t0.date, t0.modification_date, t0.shop_id, t0.storage_number,
t0.text, t0.user_id, t0.id, t1.CITY_ID, t1.LOCATION, t1.NAME, t1.CHAIN_ID, t1.SHOP_ID FROM
strimillinn.fd_receipt t0 LEFT JOIN strimillinn.fd_shop t1 ON (t0.shop_id = t1.SHOP_ID)
