Rollup fails to import component in template tag test (`.gts`)

Using the latest blueprint, I'm seeing the following behaviour when writing a component test using .gts. It errors when importing the component from the app folder.

x Build failed in 7.72s
error during build:
[vite]: Rollup failed to resolve import "my-app/components/my-component.gts" from "/<my-app>/tmp/rewritten-app/tests/integration/components/my-component-test.ts".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`build.rollupOptions.external`
