Issue: Duplicate URL with Space Prefix

When an article has a title that begins with a character that triggers a URL replacement, such that the first character is now a space, and that article is not in the default namespace, then the article's URL follows this format:

path / Namespace : Space Title

The correct URL also resolves to the same page, without triggering a 301 redirect:

path / Namespace : Title

Fixed for the next build. Since this error only occurs when generating the URL for display and not when saving it in the database, this should NOT require rebuilding any URLs.
