Review Comment:
Not really hurtful but this is changing the path the test runs. Before this
PR, the first poll on this test would return null because the member was
unsubscribed (shouldSkipHeartbeat true). Now it's because there is no
coordinator. Both go down the same path in the poll implementation but if we
want to be true to what we had before, here we should mock there is a known
coordinator, and when(membershipMgr.shouldSkipHB).thenReturn(true).
