Capture from Camera and library not working on IOS

# Bug Report

## Problem
On the latest plugin version 7.0.0, there is a problem with IOS.

### What is expected to happen?
To open the camera or library and get path of the image.

### What does actually happen?
There is no response when I call the **camera.getPicture()**.

## Information
In the cordova plugin camera 6.0.x works only using PHOTOLIBRARY but CAMERA does not. For Version 7.0.0 PHOTOLIBRARY and CAMERA no response at all.

### Command or Code
```
var get_destinationType = {
file_uri : Camera.DestinationType.FILE_URI,
data_uri : Camera.DestinationType.DATA_URL
}
var srcType = {gal : Camera.PictureSourceType.PHOTOLIBRARY, capture : Camera.PictureSourceType.CAMERA}
var options = {

quality: 100,
destinationType: get_destinationType[file_desc],
// In this app, dynamically set the picture source, Camera or photo gallery
sourceType: srcType[tp],
encodingType: Camera.EncodingType.PNG,
mediaType: Camera.MediaType.PICTURE,
correctOrientation: true
}
let cam = this;
console.log(options)
let success_img = (img)=>{
sessionStorage.setItem('uri', img);
console.log(img)


}
let error_img = (e)=>{
get_media.f7.preloader.hide();
this.f7.preloader.hide();

console.log("Error getting picture: " + e);
}
navigator.camera.getPicture(success_img, error_img, options);
}

```

## Checklist

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

Start by reproducing the no-response behavior from the navigator.camera.getPicture call using Cordova iOS 7.0.1 and camera plugin 7.0.0. Inspect the iOS configuration in CONFIG.xml, especially the camera and photo-library usage descriptions. Done means both CAMERA and PHOTOLIBRARY open successfully and return an image path or invoke the error callback.
