When closing OutboundQueue close() should go prior to finishShutdown()

When device disconnects with outstanding entries in queue segment it could occur that entry.commit() gets invoked between segment.failAll() and OutboundQueueProvider.close().
(See AbstractOutboundQueueManager#channelInactive())

Effectively there can be entries with untouched callback but in state committed. And then callback will never finish underlying rpc future object.
