title: v-list-item-title not showing title vuetify
body: <p>I am using the Vuetify sample project as reference on how to create a v-list with sub items to use as "menu" in a v-navigation-drawer.</p>
  
  <p>The Items in the List shows the Icons, but not the text.
  The sub items seems to be working correctly.</p>
  
  <p>I have updated all plugins to latest versions (including Vue and Vuetify)</p>
