the ScopedMapperTest maps the SomeObject class using the `mapper()`
function on the original Session. Therefore all SomeObject instances
are automatically saved to the Session declared in setUp(). so this
test will pass if you change setUp to read:
Session.mapper(SomeObject, table, properties={
'options':relation(SomeOtherObject)
}, save_on_init=False)
Session.mapper(SomeOtherObject, table2, save_on_init=False)
The Session.mapper function is not worth it, in my opinion, it exists
due to the sheer popularity of its previous incarnation,
"assign_mapper". I much prefer keeping things explicit.
