Bug fixes for this spec - after doing a thorough review of some the cases where we had a race condition, it all comes down to whether or not _sys1 was able to fully get MemberRemoved or whether or not it became Unreachable first. Speeding up the downing provider's decision-making process both ensures that this member gets removed quickly AND ensures that the number of retries during the HandOver process get capped so the test can complete on-time.
