Description

When using SubQueueSelectorCachePlugin to preserve consumers' selectors in network of brokers, the queues start matching all messages after consumers failover between brokers.

The underlying reason is, that SubQueueSelectorCacheBroker would cache selector TRUE for connected demand subscription, and therefore will permanently match all messages even if actual consumer reconnects.

Additionally, browsing the queue will also cause TRUE selector to be persisted.
