Modernize the test with portal_activities. This triggers another failure, but it is not a fault in this test itself. It is a problem in CMFCategory (or ERP5Type). The problem is that updateRelatedContent may be executed after reindexObject, and updateRelatedContent or notifyAfterUpdateRelatedContent does not call reindexObject. So the catalog becomes inconsistent.
