[BUG] cordova-plugin-webview-proxy doesn't play nice with navigator.mediaDevices in a cordova ios app

[ghevge]

Describe the bug
cordova-plugin-webview-proxy doesn't play nice with navigator.mediaDevices in a cordova ios app.
when cordova-plugin-webview-proxy is configured to work in an ios app, navigator.mediaDevices will always return undefined.
The source of this problem are the 2 entries in the config.xml:

<preference name="scheme" value="app" />
<preference name="hostname" value="testapp"/>

If i'll remove these 2 entries, navigator.mediaDevices will start working, but the cordova-plugin-webview-proxy will stop working

To Reproduce
Steps to reproduce the behavior: mentioned above

Expected behavior
I would expect cordova-plugin-webview-proxy not to impact other functionalities

Found a workaround, which consists in setting hostname = localhost.

<preference name="scheme" value="app" />
<preference name="hostname" value="localhost"/>
