Default tsconfig framework path to local. (vercel#644)

Testing locally it seems that `local` is what's used when there aren't any environment variables configured.

I'm making this change because `live` doesn't currently support `fs` functions and therefore cannot update the `paths[@framework]` in next.config.js.  This means deploying the commerce template from `vercel.com/live` generates an error instead of displaying the commerce page as would be displayed when running `npm run dev` locally.
