Major Description
The space description is currently imported as a space main (WebHome) page, and then the space home is a child, and then other pages are children of the home page.
This is not intended, and space home document in XWiki should be the space home page in confluence.
We decided to drop support for migrating the space description for now, as we don't have this concept in XWiki.
