> This was found by a team member while using ARI with Asterisk 14, but it probably affects all versions - 13/14/master. 
> Description is as following:
> * Once you subscribe to deviceState with Applications REST API, it will be added into deviceStateSubscription list and into subscription pool. 
> * When you unsubscribe it will remove from the deviceStateSubscription list but not from the subscription pool. 
> * When you subscribe again, it will add it to pool again. 
> * Now you will have two subscriptions and you will receive same event twice. 
> This fix should now remove deviceState subscription from pool and it should fix unsubscribe on deviceState.
> Attaching patch for quick preview, before pushing to Gerrit.
