Steps to reproduce the problem:
1. using webpack and use eval-soucemap
2. page dev url is like 'http://localhost:8078', sourceURL is like `webpack-internal:///${module.id}\n`
3. when a uncaught promise reject throw from my js, error stack is
```
at VueComponent.queryDetail (webpack-internal:///./node_modules/babel-loader/lib/index.js!./node_modules/if-loader/index.js!./node_modules/vue-loader/lib/selector.js?type=script&index=0&bustCache!./node_modules/if-loader/index.js!./helios-view/src/commonPack/biz-detail/view/page/step1.vue:229:50)
```
Chrome's native Promise global event `onunhandledrejection` not working
4.  change webpack source to make sourceUrl like `http://localhost:8078/webpack-internal:///${module.id}\n`, `onunhandledrejection` is working well now.
error stack is
```
at VueComponent.queryDetail (http://localhost:8078/webpack-internal///./node_modules/babel-loader/lib/index.js!./node_modules/if-loader/index.js!./node_modules/vue-loader/lib/selector.js?type=script&index=0&bustCache!./node_modules/if-loader/index.js!./helios-view/src/commonPack/biz-detail/view/page/step1.vue:229:50)
```

What is the expected behavior?
ignore sourceURL to make `onunhandledrejection` work

What went wrong?
sourceURL must be the same domain with page url  to make `onunhandledrejection` work

Did this work before? No
