Anssi Kääriäinen f51e409a5f Fixed #13781 -- Improved select_related in inheritance situations
The select_related code got confused when it needed to travel a
reverse relation to a model which had different parent than the
originally travelled relation.

Thanks to Trac aliases shauncutts for report and ungenio for original
patch (committed patch is somewhat modified version of that).
