title: why beforedestory is not called while refresh, but created gets called?
body: <p>I am trying to refresh page in vue.js.</p>
  
  <p>doing that causes <code>created</code> hook to get called. Why not <code>destroyed</code> hook? if <code>created</code> hook is called, it means that it should have been destroyed. Why doesn't it get called?</p>
