[vue-jest next] Cannot import relative css style

[sheremet-va]

When importing mixins inside SFC, it throws an error:

The code works with Vite.

Also the test doesn't fail and ends only after jest timer runs out.

Reproductions:

• vue file (@/components/Test.vue):

  
  <template>
  <div :class="$style.class">Test</div>
  </template>

- scss file (`@/style/_mixins.scss`):
```css
@mixin red {
   color: red
}

(Haven't actually checked reproduction, will try uploading it on github later)

While testing reproduction, I found that I have a moduleNameMapper for scss that leads to module.exports = {}

I removed it and now it works.
