attribute lang="typescript" breaks IntelliSense

[HerringtonDarkholme]

VSCode version: 1.10.2 (1.10.2)
Vetur version: 0.5.6

Vanilla VSCode, with only Vetur enabled.

Reproduction:

Open a vue file. Add a <script></script> section.

If no lang is added, completion works.

However, lang="typescript" breaks this.

Since typescriptMode is added, I expect IntelliSense completion is supported in TypeScript block.

Yes there is support for TS since #94, but it hasn't been released yet because there are some rough edges that I want to handle. There are lot of completions that don't make sense, and I think the standard is lang="ts". Also I'd like to move all language server to https://github.com/octref/vls.

I'm looking towards to release 0.6 next week, which finishes IntelliSense described in #26 and integrates #94 better.
