bug with q-app detection

[boid-com]

Quasar CLI........ v0.17.0 Quasar Framework.. v0.17.0

This is valid syntax according to official pug documentation https://pugjs.org/language/attributes.html#id-literal

However, the Quasar cli throws an error:

 app:quasar-conf Reading quasar.conf.js +0ms

⚠️  Your newer Quasar CLI requires a minor change to the root component:
   /Users/boid/Dev/boid/boidapp/src/App.vue

  Please add: id="q-app"
  to the outermost HTML element of the template.

Example:
  <template>
    <div id="q-app">
      ...
    </div>
  </template>

If I use a more verbose pug syntax:

Then quasar compiles correctly.

Also interesting to note: If you change the syntax while the webpack dev server is running, it recompiles with no issue. The error is only thrown when starting the dev server or performing a final build. I did not receive this error with previous quasar builds.

Fix will be available in CLI v0.17.2 (to be released in a few hours).
