Added exception catching in RegionSyncModule::DecodeSceneObject, return false if decoding
was not successful. Callers should check for the return (and all callers are checking
returned value now.)
Adding code to check if the returned data from DeserializeMessage() is null or not,
in RegionSyncModule.
