title: React navigation header disappear in drawernavigator
body: <p>I updated the <a href="https://reactnavigation.org" rel="nofollow noreferrer">react-navigation</a> to 1.0.0-beta.19 and now my navigator component is not working properly. The header disappeared from DrawerNavigator.</p>
  
  <p>The strange part is that I tried to restore the package to the previous version (1.0.0-beta.13), but it didn't fix it. So maybe it has nothing to do with the version update, but this is the only thing that changed.</p>
  
  <p>I checked the package in node_modules and it realy was restored to the previous version.</p>
  
  <p>What I'm curious about is that my navigator component is bad or the problem is somewhere else?</p>
  
  <p>The navigator component (bottom-up):</p>
  
  <pre><code>const AuthStack = StackNavigator({
      login: { screen: LoginScreen }
      ,forgottendPassword: { screen: ForgottenScreen }
  }, {
      initialRouteName: 'login'
      ,headerMode: 'none'
  });
  
  // HomeScreen with drawer menu
  const HomeDrawer = DrawerNavigator({
      home: {
          screen: HomeScreen
          ,navigationOptions: { drawerLockMode: 'locked-closed' }
      }
  }, {
      initialRouteName: 'home'
      ,drawerPosition: 'right'
      ,drawerWidth: 300
      ,contentComponent: props =&gt; &lt;HomeDrawerMenu {...props} /&gt;
  });
  
  // Main stack
  const MainStack = StackNavigator({
      homeDrawer: {
          screen: HomeDrawer
          ,navigationOptions: ({ navigation }) =&gt; ({
              header: &lt;HomeMenu navigate={navigation.navigate} /&gt;
          })
      }
      ,partnerList: {
          screen: PartnerListScreen
          ,navigationOptions: ({ navigation }) =&gt; ({
              header: &lt;PartnerListMenu navigation={navigation} /&gt;
          })
      }
  }, {
      initialRouteName: 'homeDrawer'
  });
  
  // Root navigator
  const Nav = StackNavigator({
      auth: { screen: ({ navigation }) =&gt; 
          &lt;AuthStack screenProps={{ rootNavigation: navigation }} /&gt;
      }
      ,main: { screen: ({ navigation }) =&gt;
          &lt;MainStack screenProps={{ rootNavigation: navigation }} /&gt;
      }
  }, {
      initialRouteName: 'auth',
      headerMode: 'none',
  });
  
  export default Nav;
  </code></pre>
