we need to try harder to find property sheets when the portal type definition does not exist.

This should fix the _baseGetMembershipCriterionCategoryList errors in trunk,
that are here because no portal types exist for some Simulation Rules:
even without portal types, we can find correctly the document class, and
perform better.
