fix: add Promise support to avoid UnhandledPromiseRejectionWarning
 fix: add Promise support to avoid UnhandledPromiseRejectionWarning on #page.on('load')# when #page.$('body')#

DavertMik: So this issue happens when an iframe doesn't have `<body>` tag inside?

+## Automating React Native apps
+
+### Problem
+Let's say we have a React Native app with component defined like this
+```html
+<Button testID='someButton'>My button</Button>
+```
+
+If you will try to execute a simple test like
+```js
+I.tap('~someButton')
+```
+it will work correctly on iOS (with XUITest driver), but on Android's UIAutomator2 it will give you an error
+```
+Touch actions like "tap" need at least some kind of position information like "element", "x" or "y" options, you've none given.
+```
+
+This happens because of the way React Native implements `testID` for Android, it puts provided value into the [View tag](https://developer.android.com/reference/android/view/View#tags),
+as could be found in the [source code](https://github.com/facebook/react-native/blob/19a88d7f4addcd9f95fd4908d50db37b3604b5b1/ReactAndroid/src/main/java/com/facebook/react/uimanager/BaseViewManager.java#L114).
+But UIAutomator doesn't have any means to work with view tags.
+
+### Solutions
+As many resources suggest (like [here](https://github.com/appium/appium/issues/6025#issuecomment-406141946) or [here](https://github.com/facebook/react-native/issues/7135)),
+you could use `testID` for iOS and `accesibilityLabel` for Android, but `accessibilityLabel` is a user-facing text that's intended for ... accesibility,
+not for UI tests, and you will need to switch it off for production builds.
+
+Another way to solve this issue is to use Espresso driver for Android.
+At first you need to enable Espresso driver for your Android configuration.
+You could do it just by changing `automationName` in the `helpers` section of the config file:
+```js
+{
+  //...
+  helpers: {
+    Appium: {
+      app: '/path/to/apk.apk',
+      platform: 'Android',
+      desiredCapabilities: {
+        automationName: 'Espresso',
+        platformVersion: '9',
+        deviceName: 'Android Emulator'
+      }
+    }
+  }
+  //...
+}
+```
+Then you could locate components using XPath expression:
+```js
+I.tap({android: '//*[@view-tag="someButton"]', ios: '~someButton'})
+```
+This way test would work for both platforms without any changes in code.
+To simplify things further you could write a helper function:
+```js
+function tid(id) {
+  return {
+    android: `//*[@view-tag="${id}"]`,
+    ios: '~' + id
+  }
+}
+```
+Now test will look more concise
+```js
+I.tap(tid('someButton'));
+```
