React-native-navigation: `disableIconTint` does not work correctly on iOS

[leolusoli]

Issue Description

Considering a pushed screen with two right buttons and a colored back button in the topBar. The back button is set via static options() method. The two right buttons are setted dinamically via Navigation.mergeOptions() method

The two right buttons always take the color setted for the backButton (ignoring disableIconTint property)

Steps to Reproduce / Code Snippets / Screenshots

Push function

    Navigation.push(this.props.componentId, {
      component: {
        name: SID_SCREEN_NAME,
        passProps: {
          // ...some props passed into the next screen
        }
      }
    })

RightButtons set by Navigation.mergeOptions

    let rightButtons = []

    if (!notFound && !loadFailed)
      rightButtons = [{
        id: this.isFavourite ? 'remove-fav' : 'add-fav',
        disableIconTint: true,
        showAsAction: 'always',
        icon: this.isFavourite ? ICONS.star_filled : ICONS.star,
      }, {
        id: 'share',
        icon: ICONS.share,
        title: 'Condividi',
        disableIconTint: true,
        showAsAction: 'always',
      }]

    // OLD V1 method
    // props.navigator.setButtons({ rightButtons, animated: true })

    Navigation.mergeOptions(this.props.componentId, {
      topBar: {
        rightButtons
      }
    })

BackButton set by static options()

  static options() {
    return {
      topBar: {
        animate: true,
        visible: true,
        drawBehind: false,
        backButton: {
          color: COLORS.darkgray,
        }
      },
    }
  }

Latest version of this library 2.20.2 has this same problem. There's not really any documentation about how this is supposed to work. Is it not possible to have an icon that's got 2 different colors?
