Description

Ensure that the heartbeat manager notifies the group manager about errors only after those errors have been handled and propagated. This is important to ensure that there is an ErrorEvent propagated to the app thread when the group manager takes actions on failures, like completing an ongoing unsubscribe (app thread should be aware of the error before the unsubscribe completes).

Consider the fix for cases then the HB receives a response containing an error code, and also for then the HB request fails (ie. network failures).
