- removed meaningless entity_name argument from session.delete()

- session.merge() propigates given entity_name to locate that mapper if the given object
is transient (and therefore has no entity_name)
- some fixes to MockEngine which still is mostly useless for most cases.
- unitofwork test used incorrect session.delete() signature
