OPC UA message response copy fails due to SOPC_DiagnosticInfo_Copy behavior
SOPC_EncodeableObject_Copy fails on any OPC UA message response encodeable type due to SOPC_DiagnosticInfo_Copy which expects InnerDiagnosticInfo field to be always non-null.
SOPC_DiagnosticInfo_Copy should manage null or non-null InnerDiagnosticInfo field value cases.
