title: Hermes is not working in Android with React-native 0.60.2
body: <p>I've upgraded React-native in existing (not new) project to 0.60.2 by way of changing package.json as written here <a href="https://react-native-community.github.io/upgrade-helper/?from=0.59.10&amp;to=0.60.2" rel="nofollow noreferrer">https://react-native-community.github.io/upgrade-helper/?from=0.59.10&amp;to=0.60.2</a></p>
  
  <p>In android/app/build.gradle I put: 
  p</p>
  
  <pre><code>roject.ext.react = [
      entryFile: "index.js",
      enableHermes: true  // clean and rebuild if changing
  ] 
  </code></pre>
  
  <p>build is successfull, but Hermes does not seems to work, in RN 0.59.0 apk was 29 Mb, now it's 46 Mb.</p>
  
  <p>If I add other changes to build.gradle as here <a href="https://react-native-community.github.io/upgrade-helper/?from=0.59.10&amp;to=0.60.2" rel="nofollow noreferrer">https://react-native-community.github.io/upgrade-helper/?from=0.59.10&amp;to=0.60.2</a></p>
  
  <p>then I get error:
  Could not read script '/Users/mac/Desktop/aqua2/node_modules/@react-native-community/cli-platform-android/native_modules.gradle' as it does not exist.</p>
  
  <p>probably because of the last line:</p>
  
  <pre><code>apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)
  </code></pre>
  
  <p>how can I solve this?</p>
