QPID-6208: [Java Broker] Avoid possibility of race condition when setting the permitted node
list

* Environment thread and broker configuration thread could race, which had the potential to
lead to the
  permittedNodeList being removed.

> It has been observed a number of times that the Permitted Nodes list has been lost on
an HA node causing unexpected intruder detection.
> On investigation is seems there is a race condition between the JE AppStateMonitor (EnvironmentStateHolder)
being registered and the JEs AppState being queried for after environment restart.  It could
therefore sometimes be NULL which caused the Permitted Nodes logic to wipe the nodes list
for the node.
