- modernized cascade.py tests

- your cries have been heard:  removing a pending item
from an attribute or collection with delete-orphan
expunges the item from the session; no FlushError is raised.
Note that if you session.save()'ed the pending item
explicitly, the attribute/collection removal still knocks
it out.
