Remove double console messages

[areknow]

All console messages are repeated twice.

Steps to reproduce:

$ vue init webpack test-app
? Project name test-app
? Project description A Vue.js project
? Author xxx <xxx@xxx.com>
? Vue build standalone
? Install vue-router? No
? Use ESLint to lint your code? No
? Setup unit tests No
? Setup e2e tests with Nightwatch? No
$ cd test-app

Make a small syntax error in a component file and save.

$ npm start

The error will be reported to the console twice. I am not sure if this is an issue with webpack or with this template.

Thank you!

Hm, you're right. Honestly - no idea where this is coming from :(
