Patch for bug in XSP.partialRefreshGet/-Post in 8.5.3

Someone made a really stupid mistake in the code for XSP.partialRefreshGet/-Post in 8.5.3..

I won't go into specifics of the code as I'm uncertain if it's breaking some license. Let's just say that if they moved a line of code four or five lines upwards, there wouldn't be any bug.

I wrote a simple patch for the bug. Put it in a CSJS library, and your code will work like it did on 8.5.2 (unless I made a stupid mistake).

/**
 * Fix for bug with partialRefreshGet/-Post in 8.5.3
 */
(function(){
 var oldPartialRefreshGet = XSP.partialRefreshGet;
 XSP.partialRefreshGet = function( targetId, options ){
  // Convert to array
  var argsArray = Array.prototype.slice.apply( arguments );
  
  if( argsArray.length > 1 ){ argsArray[1] = argsArray[1] || {}; }  
  if( argsArray.length === 1 ){ argsArray.push( {} ); }
  
  oldPartialRefreshGet.apply( XSP, argsArray );
 };
 
 var oldPartialRefreshPost = XSP.partialRefreshPost;
 XSP.partialRefreshPost = function( targetId, options ){
  // Convert to array
  var argsArray = Array.prototype.slice.apply( arguments );
  
  if( argsArray.length > 1 ){ argsArray[1] = argsArray[1] || {}; }  
  if( argsArray.length === 1 ){ argsArray.push( {} ); }
  
  oldPartialRefreshPost.apply( XSP, argsArray );
 };
})();

This code should be forwards compatible with future API updates, as it doesn't assume number of arguments in function.
