title: Vetur bug on Vue 2 on "random" files
body: <p>I have a bug on my project since yesterday, vetur is showing vues template part in red (&quot;Cannot find name 'xxx' &quot; on every words)
  I tryed a lot of things (tsconfig.json, .eslintrc.js, other extentions, modify vetur settings...) and I didn't find any solutions for my case

  <p>vetur v0.35.0 vscode 1.61.2 vue 2.6.14</p>
