Linq query with "Contains" on persistent collection fails

[v-kabanov]

Code like

                    session.Query<GrandChildEntity>()
                        .Where(e => parent.Children.Contains(e.Parent))
                        .FirstOrDefault();

worked in v4, but fails in v5.
Self-contained test: https://github.com/v-kabanov/Nh5Regression/blob/master/ContainsSubquery.cs

By the way, the persistent collection in that test is loaded eagerly despite being mapped as lazy.

Not when I run it. It immediately lazy loads it, though. /G

[v-kabanov]

Yes, I was wrong, lazy loading was triggered by debugger.
Added assertion in the linked test.
