title: Vuetify v-select value not returning key
body: <p>I am trying to v-model the keys from this data from my v-select :</p>
  
  <pre><code>{
  data: {
  IT: "Italy",
  PL: "Poland",
  AF: "Afghanistan",
  AX: "Aland Islands",
  AL: "Albania"
       }
  }
  </code></pre>
  
  <p>My v-select and output look something like this (this is as close as i can get:</p>
  
  <pre><code>        {{ this.model[0] }}
  
          &lt;v-select
          :items="Object.entries(this.items)"
          v-model="model"
          &gt;
        &lt;/v-select&gt;
  </code></pre>
  
  <p>The problem with this, is the value of the v-select will be "IT, Italy", when i just want Italy</p>
  
  <p>I've been trying to work out ways, such as using a helper function to search the value and return a key, but i keep getting undefined, and wonder if there is an easier way of doing this. Or maybe converting the data to a new object.</p>
  
  <p>If anyone has any ideas i would greatly appreciate it!</p>
