Consistent handling of base between preloadCode and preloadData #10398
Description
Describe the problem
When using base in a project, preloadCode works only if I give it a path excluding base. preloadData works only if I give it a path including base. Additionally, preloadData will error if no paths match but preloadCode does not.
With the combination of these issues and no immediate visible impact on the application, it is very easy to have preloadCode calls that are broken and do nothing. Tracking them down inside an application of any size is difficult.
Repo to test: https://github.com/WaltzingPenguin/sveltekit-preload
Describe the proposed solution
preloadCode should require base as part of the path to match preloadData (and goto). preloadCode should also throw an error if it did not match any routes.
