Trevor Parscal 16310f7535 Added tests and fixed inconsistencies for empty text node handling
Continues where Ibb682332a6084e357104183641a104e3ae1e253f left off, adding tests and removing inconsistencies between the behavior of the document constructor, which was adding empty text nodes to empty paragraphs, and correcting other tests which expected empty text nodes to be there as well.
