SmartClient 6.5.1: patch for issue with RestDataSource and dataProtocol 'postMessage'

[Isomorphic]

In SmartClient release 6.5.1 in some cases a RestDataSource with operationBindings' dataProtocol set to 'postMessage' can cause a JS error when performing operations.
This patch will avoid this error.

//----------------------------------------------------------------------------
// Isomorphic SmartClient 6.5.1 patch
// Purpose: Fix for a case where REST dataSources could experience JS Errors 
// if dataProtocol was set to 'postMessage' for some operations.
// 
// Applies to SmartClient 6.5.1 build only
