SubscribeToPresence publisher worker should fail trackable if channel attach fails

[AndyTWF]

At the moment, the EnterPresenceWorker fails the trackable if the channel attach fails (enters a FAILED state) whilst the worker is waiting. This allows the consumer to decide what to do next. However SubscribeToPresenceWorker does not, we should fail the trackable in this instance for consistency.
