Cannot compile <template> part of single file component?

I am trying to switch to TypeScript from Babel, but getting unexpected behavior, it throws `[!] Error: Unexpected token`.

If I separate `<template>` part into HTML files and load it from `<template src=".html">`, build finishes without error.

### Steps to reproduce the behavior

1. Clone `typescript` branch of https://github.com/1000ch/vue-grd.
2. `npm install`
3. `npm run build`
