ContinuousQuery instance should be the same if Search.continuousQuery() is used

The static method Search.continuousQuery(<CacheName>) will always return a NEW ContinuousQuery instance, to handle such it should return alway the same instance as this would enhance the handling
From a user perspective it is unexpected as it is possible to use Search.continuousQuery().register... and this is working but .unregister* will not find any of the registered Listeners because of the different instance.
