Fixed initializePortalTypeDynamicProperties.

When the function was called on a new Portal Type (not present in aq_portal_type)
with recursive = 1, no Accessor was generated, and the Portal Type was added to aq_portal_type,
thus preventing a future call of initializePortalTypeDynamicProperties to generate anything.

I just removed the recursive argument, and ajusted the recursive call to use parent_object instead of self,
which should allow to recursively create Workflows Accessors.
