Comment:
I've created a sloppy patch to fix this issue. It's my first whack at
working on the DB layer (or making a serious contribution) so please bear
with me.
I figured that we need a reference to the SingleRelatedObjectDescriptor
that is related to the ReverseSingleRelatedObjectDescriptor for the
OnToOne field so that we can access it from the '__set__' method of the
ReverseSingleRelatedObjectDescriptor to remove the cache from the object
that the relation previously pointed to. So I added the
'related_object_descriptor' attribute to the RelatedField object. Not sure
if I should rather add the attribute in a more appropriate place, like in
RelatedObject or ReverseSingleRelatedObjectDescriptor itself.
