radicle/cob/identity: Fix cascading_rejections test to test actual cascading 

The test previously had B2 as a sibling of B1 (both children of A1),
because update() always uses self.current as parent. This meant
the test was testing multi-sibling rejection, not cascading.

Now B2 is a child of B1 via a manual transaction, so when B1 is
rejected (sibling E1 accepted), B2 is rejected via RejectedBy::Parent
(cascade), which is what the test name promises.
