The failing test expects a specific migration to fail when a step-down of the donor interrupts the sequence.
Such condition is generally true: nevertheless, when a step-down of the config server node follows the step-down of the donor, the failing migration may be re-attempted as part of the balancer recovery sequence and hence succeed.
The BF may be corrected by modifying such assert condition.
