Two problem when using with vue-cli 3.0-beta.6

[zhangbobell]

Thanks for providing such a cool plugin but when I use this latest version(v4.0.1) with vue-cli 3.0-beta 6:

1. need to use "presets": ["@babel/preset-env"] not "presets": ["env"]. If not, you'll encounter Error likeTypeError: Cannot read property 'bindings' of null
2. h auto injection seems invalid, I have to manually add h: CreateElement to render function parameter. If not, output error behaviors like #65

maybe need to get updated ?
