[3.2.x] Fixed #32650 -- Fixed handling subquery aliasing on queryset combination.

Browse Source 
This issue started manifesting itself when nesting a combined subquery
relying on exclude() since 8593e162c9 but
sql.Query.combine never properly handled subqueries outer refs in the
first place, see QuerySetBitwiseOperationTests.test_subquery_aliases()
(refs #27149).

Thanks Raffaele Salmaso for the report.
