[PayPal] Fixed bug with currency code not found

[patrickbussmann]

Hey guys,

I'm getting this error while using the ionic-native PayPal plugin.

PayPal SDK: PayPalPayment not processable: Currency code is required.

I'm using this code:

PayPal.init({
  "PayPalEnvironmentProduction": "YOUR_PRODUCTION_CLIENT_ID",
  "PayPalEnvironmentSandbox": "YOUR_SANDBOX_CLIENT_ID"
}).then(() => {
  let payment = new PayPalPayment('1.23', 'EUR', 'Charge money', 'intent');
  PayPal.renderSinglePaymentUI(payment).then((s) => {
    console.log('SUCCESS RENDER INIT', s);
  }, (e) => {
    console.log('ERROR RENDER INIT', e);
  });
}, (e) => {
  console.log('ERROR PAYPAL INIT', e);
});

Explanation of this issue:
The PayPal-Cordova-Plugin uses the currency from the array instead currencyCode so that this can never work. See https://github.com/paypal/PayPal-Cordova-Plugin/blob/master/src/ios/PayPalMobileCordovaPlugin.m#L97

The official JS file says the same. See https://github.com/paypal/PayPal-Cordova-Plugin/blob/master/www/paypal-mobile-js-helper.js#L49

After this change it works fine 👍
