XFA - Elements created outside of XML must have all their properties (bug 1722029)

- an Image element was created, attached to its parent but the $globalData property was not set and that led to an error.
  - the pdf in bug 1722029 has 27 rendered rows (checked in Acrobat) when only one was displayed: this patch some binding issues around the occur element.
