Subscribe for a data item first time adds the DI to internal SSO client list. When the request comes for after this, since item is already added, dataItemsToSubscribe will be empty. So the code for request value for DI is not invoked. Handle this scenario in SSO. Change-Id: Ife04fe4eedc9b3132e7967f781b0e29ac41c01e7 CRs-Fixed: 2347338
