When a queue member has unacknowledged messages and is leaving the
group, these messages are supposed to be immediately redelivered
to existing queue members. However, if a target member had unack'ed
messages of a sequence lower than the reassigned messages these
reassigned messages would not be redelivered until after the AckWait.
The issue was introduced in PR #729
with the incorrect change in ordering algo for the messages that
should expire.
Resolves #869
