title: Ionic deletes lines of code in json/i18n file during deploment process
body: <p>I have a really strange bug in my Cordova Application.</p>
  
  <p>I am using the i18n <a href="https://ionicframework.com/docs/v3/developer-resources/ng2-translate/" rel="nofollow noreferrer">ngx-translate plugin</a>. It works good. But know it is a little bit buggy. If I add a new line in the de.json or en.json file and build or run the app, the new lines will be removed. It is not possible to add new lines anymore. </p>
