Vetur crashes if checkJs is set to true and a vue file which modifies a watched value is opened

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: Linux
• Vetur version: 0.11.7
• VS Code version: 1.21.1

Problem

When checkJs is set to true in tsconfig.json or jsconfig.json and a .vue file which modifies a watched value is opened, Vetur crashes.

Vetur crashing on files like this is almost identical to https://github.com/vuejs/vetur/issues/191#issuecomment-300405883

There is no output from Vue Language Server as it appears to crash. However, there is output from the Window log:

Reproducible Case

Open nextgensparx/veturpack in VS Code and then client/components/Test.vue.

It’s worth noting that if data2 is changed to data3 in watch, the issue goes away.

[octref]

This seems to be solved in TS 3.3, which you can get by:

• yarn add -D typescript@3.3 in workspace
• "vetur.useWorkspaceDependencies": true

See #682 for details.

This issue will be completely gone after #1163.

@HerringtonDarkholme Can this be fixed now that https://github.com/Microsoft/TypeScript/issues/23198 has been closed? The latest version of Vetur (0.16.2) still crashes on the reproduction repository mentioned above.
