"exclude" by annotation works like "filter"

[Pavel Anossov]

"Exclude" by annotation does not negate lookup parameters:

>>> [g.num for g in Group.objects.annotate(num=Count('sites')).exclude(num=73)]
[73]
>>> [g.num for g in Group.objects.annotate(num=Count('sites')).filter(num=73)]
[73]

>>> e = Group.objects.annotate(num=Count('sites')).exclude(num=73).query.as_sql()
>>> f = Group.objects.annotate(num=Count('sites')).filter(num=73).query.as_sql()
>>> e == f
True

>>> Group.objects.annotate(num=Count('sites')).exclude(num=73).query.as_sql()
(u'SELECT (...), COUNT(`sites`.`id`) AS `num` FROM `site_groups` LEFT OUTER JOIN `sites` ON (`site_groups`.`id` = `sites`.`group_id`) GROUP BY site_groups.id HAVING COUNT(`urls`.`id`) = %s  ORDER BY NULL', (73,))

[Pavel Anossov]

sorry, there should be sites in HAVING as well, of course :)

(In [9785]) Fixed #10100 -- Corrected handling of the negation required exclude() clauses that reference aggregate columns. Thanks to Anossov for the report.
