Vue scoped css only work in nomodule

[Austaras]

Steps to reproduce:
Add following code to vue-cssextract example

<style scoped>
.foobar {
  font-family: mono
}
</style>

and add foobar class to some html element
reason of bug:
the above css is compiled to .foobar[data-v-xxxxxx], however for different target vue generate different hashed id, so only in legacy mode would scoped css work
