> Per CAY-2478 we can generate properties for PK attributes. But they are incompatible
with {{dot() }} operator as it is unaware about db paths. 
> Simple test case: {code}
> Expression exp = Painting.TO_ARTIST.dot(Artist.ARTIST_ID_PK_PROPERTY).eq(1L);
> {code}
> Will generated following expression: {{toArtist.null = 1}}
