Sample project showing Vitest base path bug

When the base path set in svelte.config.js is equal to the beginning of the actual project path vitest fails because it resolves the node_modules path incorrectly.

Steps to reproduce

If you are on macOS simply:

• clone this sample repo somewhere into your home directory (path to project starts with /Users)
• try to run npm run test

If you are on another OS:

• clone this sample repo somewhere on your machine and replace in svelte.config.js in the line base: "/Users" the "/Users" by the beginning of your project path.
• try to run npm run test
