Can't auto import Typescript classes in SFC

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: Win
• Vetur version: 0.17.1
• VS Code version: 1.32.3

Problem

If you click quick fix (or ctrl+.) it shows...

Reproducible Case

similar to #606

• In VSCode create a new project with vue cli vue create .
• Typescript only
• Component classes
• Go to App.vue and comment out the line import HelloWorld from './components/HelloWorld.vue';
• Hover over HelloWorld under components

(per #682 setting "vetur.useWorkspaceDependencies": true and using Typescript ^3.3 does not help)

I would fix it together with #907 (currently path is messed up).
