What you found (yes I know I'm super late to this) was an edit which transcluded the wordmark file on the page. If you look at the history of File:Wiki-wordmark.png, though, you'll find that logo did not say Tardis Data Core at the time. Like Digifiend said, the file was updated on 10 January 2013 to reflect the new name of Tardis Data Core.
Also, strictly speaking, the wiki was founded on 11 November 2004 by user:Mantrid, and the date you give was in fact the first edit. It is not necessarily known who was the IP user who made this first edit, but it may well have been user:Freethinker1of1. He is not, however, the founder, despite what he may have claimed when he was around. See Tardis:About for more information.
