Drop left-over activities between tests

On Zope 2.12, in test files with multiple test classes, activities from one test class are reactivated on the next test class.

This doesn't happen on Zope 2.8 by pure accident: during portal construction, the skin is not properly configured, and so
activities are not reactivated as they are on Zope 2.12.
