Script with lang="ts" should be typescript-ed

Otherwise build with .vue component files will fail.

I see. My change is only needed when ExtractTextPlugin is used when you want to extract styles from SFC into separate .css file. It's a big gotcha, not really sure why it is happening.

@octref @HerringtonDarkholme any idea about whether this change sounds appropriate?

I can reproduce building error if setting extractCSS to true. https://github.com/vuejs/vue-loader/blob/master/docs/en/configurations/extract-css.md

Hmm, it seems to be a bug in vue-loader though. I need some more investigation.

Update: it seems to be vue-loader's behavior. If extractCSS is true, it will consult css-loader if loaders[lang], in this case 'ts-loader', is not explicitly configured. https://github.com/vuejs/vue-loader/blob/master/lib/loader.js#L216-L218

Fix has been released as 12.0.4.

@zigomir can you try out the latest ts-loader and see if that helps with the issue you ran into?

[zigomir]

Yes, this fixes it! Thanks @HerringtonDarkholme and @DanielRosenwasser!
