[Pacemaker] prevent the resource's start if it has "stop NG" history on the other node

It seems that the current Pacemaker does shutdown in spite of
unmanaged resources when "stonith-enabled=false",
so one unmanaged resource in group should be ignored during shutdown process.
By the way, I tried Master/Slave setup which contained the above group
resource without stonith ("stonith-enabled=false"),
Pacemaker shutdown went well and Master resource's fail-over was also
successful.
The above simple group behavior(prevents "shutdown") is peculiarity.

Actually, it's desirable to "prevent Pacemaker shutdown" if there are
unmanaged resource,
but this behavior has been changed?
# I found an old changelog, it said "High: crmd: Bug LF1837 -
Unmanaged resources prevent crmd from shutting down"
