IAB is opening the locally installed app not the webpage

# Bug Report

## Problem

Loading a page opens the installed app on the device. For example, loading a facebook page will open the Facebook app.

### What is expected to happen?
Just load up the page

### What does actually happen?
Opens app instead.

## Information
`target=_blank` and `usewkwebview=yes`

### Environment, Platform, Device
iOS 13.3.1

### Version information
IAB 3.2

## 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 by reproducing the behavior on iOS with target=_blank and usewkwebview=yes, using the reported Facebook-page example and environment. Then trace the plugin's iOS handling of links that resolve to installed apps; done when the page loads in the in-app browser instead of opening the device's app.
