 The following test (added to `tests/queries/test_qs_combinators`) fails
 when trying to exclude results using OuterRef()


 {{{
 def test_exists_exclude(self):
     # filter()
     qs = Number.objects.annotate(
         foo=Exists(
             Item.objects.filter(tags__category_id=OuterRef('pk'))
         )
     ).filter(foo=True)
     print(qs)  # works

     # exclude()
     qs = Number.objects.annotate(
         foo =Exists(
             Item.objects.exclude(tags__category_id=OuterRef('pk'))
         )
     ).filter(foo=True)
     print(qs)  # crashes

     # filter(~Q())
     qs = Number.objects.annotate(
         foo =Exists(
             Item.objects.filter(~Q(tags__category_id=OuterRef('pk')))
         )
     ).filter(foo=True)
     print(qs)  # crashes
 }}}


 It results in the following error

 {{{
 ValueError: This queryset contains a reference to an outer query and may
 only be used in a subquery
 }}}
