XWiki PDF export should demarcate lists elements between one another.

[oanalavinia]

Steps to reproduce:

1. Create a new Diagram
2. Add some text shapes that contain lists
3. Click Save & View
4. Access More actions > Export > Export as PDF > Export

If you have lists elements that are taking more than just a row ( the text is wrapped), you won't be able to differentiate the rows

More info - lists will be delimited by a bullet, regardless of what is chosen as a delimiter
