Inconsistent behavior of one-to-one relation through PK with lazy="no-proxy" 
-----------------------------------------------------------------------------

                 Key: NH-2716
                 URL: http://216.121.112.228/browse/NH-2716
             Project:  NHibernate
          Issue Type: Bug
          Components: Core
    Affects Versions: 3.2.0Beta1
            Reporter: Boyan Trushev


This is a follow-up of the problem I described in #NH-2704. While I was debugging the issue there I found another problem that concerns the case when the one-to-one relation is though PK and lazy is set to "no-proxy". The issue can be easily reproduced with the existing LazyOneToOne test case. You just have to duplicate the assert that checks if p2.Employee is null:

p2 = s.CreateQuery("from Person where name='Emmanuel'").UniqueResult<Person>();
Assert.That(p2.Employee, Is.Null);
Assert.That(p2.Employee, Is.Null);

If you run the Lazy() test case now you will see that it fails on the second assert. 

On the first "Assert" the Employee property returns null as it is still not loaded (not contained in loadedUnwrapProxyFieldNames) and the EmployeeProxy which is contained in the field is unwrapped. After the first access however the fieldName is added to loadedUnwrapProxyFieldNames and on the next property access the EmployeeProxy is no more unwrapped.
