bug: (next) Missing line break before const cssModules causes module load error

[weaverryan]

Hi!

Fixes an edge case: if you have multiple style and the 2nd one is a module, it will cause a build failure:

<style lang="css">
</style>

<style module>
</style>

Internally, this builds:

import "./App.vue?vue&type=style&index=0&lang=css"const cssModules = script.__cssModules = {}
import style1 from "./App.vue?vue&type=style&index=1&module=true&lang=css"
cssModules["$style"] = style1

Notice the missing line break before const cssModules =.

Apologies for no test... but I can't seem to find any for next :).

Cheers!
