title: cordova-plugin-firebase how to remove crashlytics?
body: <p>I have installed <a href="https://github.com/arnesson/cordova-plugin-firebase" rel="nofollow noreferrer">cordova-plugin-firebase</a> in an Ionic Cordova application and since I have added this plugin I notice the following error when I debug my app with Xcode</p>
  
  <blockquote>
    <p>[Fabric] failed to download settings Error Domain=FABNetworkError Code=-5 "(null)" UserInfo={status_code=403, type=2, request_id=..., content_type=application/json; charset=utf-8}</p>
  </blockquote>
  
  <p>I don't want to use Fabric/crashlytics in any case</p>
  
  <p>How could I remove it without affecting the Cordova Firebase plugin?</p>
