DefaultIfEmpty not supported when used with a GroupBy

Description

The following query will generate a System.NotSupportedException : The DefaultIfEmptyResultOperator result operator is not current supported

from o in session.Query<Order>()
from ol in o.OrderLines.DefaultIfEmpty()
group ol by ol.Manufacturer into grp
select new {grp.Key}

This relates to NH-2379.

I will provide a failing test and a fix shortly.

Ricardo, do you mean NH-3027?

Still not possible to group by a full entity, just by one or more of its properties, right?
