title: How to use date DatePipe with ngx-translate
body: <p>I have this translation defined:</p>
  
  <p>"...has created <strong>{{param1}} ({{param2}})</strong> on {{ param3 | date:'mediumDate' }}, {{ param3| date:'shortTime' }}"</p>
  
  <p>param1 and param2 get replaced but param3 is not ({{ param3 | date:'mediumDate' }}, {{ param3| date:'shortTime' }} is printed)...how can I use the datepipe inside a translation?</p>
