Anssi Kääriäinen 3c6318e831 Fixed #19870 -- Regression in select_related in inheritance cases ...

There was a regression in case two models inherited the same parent,
and one contained a foreign key to other. When select_related travelled
the foreign key the other model reused the parent join made by the
first model. This was likely caused by Query.join_parent_model()
addition in commit 68985db48212c701a3d975636123a5d79bdc006f.

Thanks to Trac alias loic84 for report & tests.
