[WS] Incoming Subscription 'dhcp_statistics'

not sure whats going wrong here?

Thanks for pointing this out @hijak. I presume this error is being caused due to the incorrect usage of Promises in API calls. Not sure how to reproduce the exact condition but similar errors have been raised at different API call points. Will fix the common source code and commit asap.
