Non-canon things can contain canon information-After all, fanfiction is noncanon, but it still gets canon facts correct, at least.. some of them. It doesn't mean all the information is wrong, but rather, it's noncanon, and should therefore be dismissed. Dismissing the tweet about Asgore doesn't change the fact that Undyne said nobody made it past Asgore-That happens in-game. Dismissing fanfiction about the Amalgamates (Dogs of Future Past anyone?) doesn't change the fact that Alphys did indeed create the Amalgamates. The tweets aren't canon, but they're not "reverse-canon" either.

I said it was good for Temmie that he fixed the mistake-Clearly, Toby meant it to be the way Temmie fixed it, if it was changed in a patch.

Yes, not everything was perfect when the game came out. I even pointed out a paradox that existed at one point. That's what patches are for. ;)

Indeed, the art book isn't canon to the world of Undertale. It's only canon to ITSELF. Same thing for the kickstarter, which has this line:

"Guzusuru drew the kickstarter thumbnail and will be assisting with animations in the full game."

Animation's a part of programming-Therefore, Guzusuru helped with the programming:Toby's just the MAIN programmer. As a result, the development of Undertale is STILL not correctly told.
