title: Angular i18next empty translation?
body: <p>Is it possible to set up Angular's i18next provider so that it wouldn't show any value when the value for the key is not defined. </p>
  
  <p>The problem is that if for instance  for the key <code>my:key</code>I don't have any translation defined. I would like to show only empty string istead of <code>my:key</code> in the template.</p>
