No, it's still canon. They just remade certain levels from it in Contracts. But I don't recall anything being retconned. 47's still a science experiment, still killed his maker. The story wasn't very intensive in the first game, but what little that was there is still relavent as far as I know. They even make a reference to the scientist that created him in Absolution.
Though, honestly, the missions they remade for Contracts were probably the highlights of it anyway. I was never a big fan of the Colombia (that's where the jungle missions were, right?) missions.
