Debug works incorrectly

[sobolevn]

Hi, I have a problem with vscode debugging.

Steps to reproduce:

1. clone master branch
2. open vscode
3. add <button @click="hello">Hello</button> to template in Component.vue
4. set breakpoint inside hello() method, also set some breakpoints inside store/index.js
5. run yarn and yarn dev in embed terminal
6. run debuuger
7. click Hello button

I can illustrate what actually happens:

And I had no luck in reaching these breakpoints.

However, it is possible to debug store with no problems.

Original issue: vuejs/vue-loader#1163

After reading this comment vuejs/vue-loader#1163 (comment)
I have tried to update babel-core to 6.26.3, but it still does not work.

Yes, the issue is really a sourcemap issue. Until vuejs/vue-loader#1163 is completely solved nothing I can do here.
