title: Cannot find name 'Headers', 'RequestInit', 'Response'
body: <p>I updated my nativescript from the 2.5.2 to the 3.0.3. And suddenly when I try to run the app I get the following errors:</p>
  <blockquote>
  <p>node_modules/tns-core-modules/tns-core-modules.d.ts(17,27): error
  TS2304: Cannot find name 'Headers'.</p>
  <p>node_modules/tns-core-modules/tns-core-modules.d.ts(19,44): error
  TS2304: Cannot find name 'RequestInit'.</p>
  <p>node_modules/tns-core-modules/tns-core-modules.d.ts(19,66): error
  TS2304: Cannot find name 'Response'.</p>
  </blockquote>
  <p>I don't understand why, because I think I'm not using this modules in my project.</p>
  <p>Thanks! :)</p>
