#21297: CurrentSiteManager returns objects of superclass for models that do not
define any additional fields

Suppose I have two models, one inheriting the other:
{{{
class BaseModel(models.Model):
title = models.CharField()
# ...
objects = models.Manager()
on_site = CurrentSiteManager()
}}}
Then I create a subclass:
{{{
class SubModel(BaseModel):
objects = models.Manager()
on_site = CurrentSiteManager()
# ...
}}}
Then calling SubModel.on_site.all() returns a QuerySet containing all
instances of BaseModel on that site. Checking the SQL reveals that that no
table join to the sub_model table occurs.
This can be worked around by instead calling
{{{SubModel.objects.filter(site=settings.SITE_ID)}}}, but I do believe
this to be a bug.
