QPID-7933: [Java Broker] Ensure changes made to existing durable children of virtualhost after virtualhost restart are persisted

> If a *virtualhost* is stopped, the object's children are closed and evacuated from memory. On restart, the children are recovered from the store. However, the restart path AbstractVirtualHost#onRestart fails to reinstall the StoreConfigurationChangeListener on the recovered children. The effect of this is that subsequent changes made to *existing* durable children (for instance, a queue's alert threshold) are not persisted to the configuration store.
> The persistence of newly added objects (or the deletion of existing objects) is not affected. This is because the VirtualHost still has its StoreConfigurationChangeListener intact. (The virtualhost is not closed during a restart).
> A restart at the virtualhostnode level does not suffer this problem.
