== Problem Description
I'm reducing some Q objects (similar to what is described in ticket:32554.
Everything is fine for the case where the result is
`ExpressionWrapper(Q(pk__in=[]))`. However, when I reduce to
`ExpressionWrapper(~Q(pk__in=[]))` the query breaks.
== Symptoms
=== Working for `ExpressionWrapper(Q(pk__in=[]))`
{{{#!python
print(queryset.annotate(foo=ExpressionWrapper(Q(pk__in=[]),
output_field=BooleanField())).values("foo").query)
}}}
{{{#!sql
SELECT 0 AS "foo" FROM "agri_data_declaration"
}}}
=== Not working for `ExpressionWrapper(~Q(pk__in=[]))`
{{{#!python
print(declarations.annotate(foo=ExpressionWrapper(~Q(pk__in=[]),
output_field=BooleanField())).values("foo").query)
}}}
{{{#!sql
SELECT AS "foo" FROM "agri_data_declaration"
}}}
