Invalid XML when calling .addText() with empty array.

[JimmyTheChimp]

I'll try to nail down some more details when I get a chance, but basically something along the lines of the following code causes invalid XML to be generated and PowerPoint will require a "repair" operation to open the file. The file does not display correctly even when repaired.

var dataDrivenTextArray = [];
slide.addText(dataDrivenTextArray,
  {
    x: 1,
    y: 1,
    w: 2,
    h: 0.5,
    valign: 'top'
  });

I've attached an example of the corrupted output.

Hi @JimmyTheChimp ,

Thanks for reporting this.

The library correctly handles empty arrays now.
