#14163: Setting pk should set the related fields also in the base chain.

Keywords: Inheritance, parent_link, OneToOneField | Stage: Unreviewed

-----------------------------------------------------+----------------------
Consider two models:
{{{
class A(models.Model):
pass
class B(A):
a = models.OneToOneField(A, parent_link=True, primary_key=True)
}}}
creating an b instance and setting its pk should also set the a.id:
{{{
>>> b = B(pk=1)
>>> b.pk
1
>>> b.a_id
1
>>> b.id
1
}}}
At the moment we will get:
{{{
>>> b.id is None
True
}}}
It would be even better if setting b.id would also set b.a_id, but that is
harder to do, and maybe it isn't that important.
