remote-mediawiki: skip virtual namespaces

Virtual namespaces do not correspond to pages in the database and are automatically generated by MediaWiki. It makes little sense, therefore, to fetch pages from those namespaces and the MW API doesn't support listing those pages. According to the documentation, those virtual namespaces are currently "Special" (-1) and "Media" (-2) but we treat all negative namespaces as "virtual" as a future-proofing mechanism.
