Creator and Lastmodifier lost after XML import

Some fields like creator and lastmodifier are lost after an xml import. (They are correctly set in the xml file) which results in the below miss behaviours:

• Users lost their personal spaces post xml import, and are unable to create a new one.
• Confluence questions sections are broken and no longer work post xml import.

Work around:
