Localization extension - complex entity class hierarchies and projection to custom types

[beercsaba]

Projection to custom types does not work (throws exception) when model uses complex class hierarchy with abstract properties.

From ProjectionToCustomTypesTests.ComplexClassHierarchyTest() method:
session.Query.All<BuiltinMessage>().OrderBy(e => e.Identifier).Select(e => new { e.Identifier, e.Name, e.Enabled, e.Description })

throws this exception:
Xtensive.Orm.QueryTranslationException : Unable to translate 'Query.All().OrderBy(e => e.Identifier).Select(e => new @<Identifier, Name, Enabled, Description>(
e.Identifier,
e.Name,
e.Enabled,
e.Description
))' expression. See inner exception for details.
----> System.NotSupportedException : Field 'e.Name' must be persistent (marked by [Field] attribute).
