Fix template rendering inclusion of dc:description field should not include <p/> to be displayed

Steps to reproduce:

• Create a new template of document using CompositionMP.docx
• Choose for listeingredients the type "inclusion", and as source the XPath "dc:description"
• Choose as generation engine:
  XDocReportProcessor and as rendering: PDF
• In a workspace, create a Note document and fill the description field with some random text
• Associate the template created above to the Note you just created
• Generate the rendering => the field description is not displayed
• Change the random text of the description of the Note to prefix it with <p/> and suffix it with <p/> and generate the rendering: the description then is displayed, misaligned.
• Remove the <p/> prefix and suffix from the description fo the Note document
• change the template from "inclusion" to "document property" type
• Go back to the Note, "reinitialize the parameters" in the "associated models" tab, and generate the rendering: the description is then displayed, aligned.

Thus, the dc:description field seems mistreated when used in the "inclusion" type.

It appears the same for PDF, ODT and DOCX types.
