Description
In the 2.2.x version it was possible to do first an intersection and after that a filter or exclude on the resulting query set.
Now it leeds to an error.
The error says
django.db.utils.NotSupportedError: Calling QuerySet.filter() after intersection() is not supported.

Yes it was possible to call
QuerySet.filter()/exclude()afterQuerySet.intersection()/union()/difference()but these calls were ignored, i.e. they didn't affect combined queries. That's why we decided to raise a descriptive error (see #27995).
