Fix in EnableRemoteService for Notification Service via Cloud

Fix in EnableRemoteService for Notification Service via Cloud

When notification message is sent thru cloud, consumer cannot receive.

It worked well from initial development environment
but others reported it does not worked well in some environment.
Initially, to call NSSetRemoteServerAddress(char *serverAddress)
resolves issue by testing but, logic perspective, this is not solution.

MSCacheSubData has messageObserverID, syncObserverID for local and
remote consumer respectively and this structure brings fundamental
complexity inspite they are not handled separately.
This patch remove remote set for these observerIDs member from struct.
