cordova.InAppBrowser.open don't work on second and following app starts IOS

# Bug Report

## Problem
I upgraded Cordova from 7 to 8.1.2 and cordova-ios from 4.5.5 to 5.0.0 and now the inAppBrowser don't work as expected.

### What is expected to happen?
The inAppBrowser should always open the specified URL.

### What does actually happen?
I'm installing the APP.
The app is opened, it starts, then I open the inAppBrowser. The specified URL is loaded.

I close the app so that it is no longer active in the background.
I open the app again, it starts, then I open the inAppBrowser. The specified URL is not loaded. Only about:blank is displayed. This behavior will remain until I delete and reinstall the app

## Information
I am currently installing the plugin from the master branch. But it doesn't work on the 3.0.0 either.
This is how I open the inAppBrowser
` var options = "location=no,clearcache=yes,clearsessioncache=yes,zoom=no,hardwareback=yes"`
`var ref = cordova.InAppBrowser.open(encodeURI(myurl), '_blank', options);`

I don't know if you need more Information, I can also provide a video if necessary.
I use the UIWebView

### Command or Code
See above

### Environment, Platform, Device
It only happens on ios.
I'm testing on an iPhone X, IOS 12.1

### Version information
Cordova CLI: 8.1.2
Cordova IOS: 5.0.0
Xcode 10.1

Other Plugins i use:
cordova-plugin-splashscreen

## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Start with the cordova.InAppBrowser.open call and the iOS UIWebView behavior described in the report. Reproduce the first launch and subsequent-launch sequence on iOS, then trace the InAppBrowser lifecycle; done means the specified URL loads after reopening the app without reinstalling it.
