title: Notifications failing at notify()
body: <p>I am trying to fire a simple <a href="https://next.quasar.dev/quasar-plugins/notify" rel="noreferrer">notification </a> in Quasar 2:</p>
  <pre><code>setup() {
    const $q = useQuasar()
     $q.notify('hello')
  }
  </code></pre>
  <p>This fails with:</p>
  <pre><code>Uncaught TypeError: $q.notify is not a function
  </code></pre>
  <p>This is a UMD application that works fine without these two lines - I do not really know where to go from there as the docs say that there is nothing special to configure before using it.</p>
  <p>Incindentally, my IDE is suggesting me <code>notify()</code> when typing <code>$q.</code> so at least at that level is it well recognized.</p>
