fix: force hostname to lowercase

[erisu]

Motivation and Context

Fixes #1426

Per comment #1426 (comment)

There might be an underlining issue within the Android WebView and how it is not honouring the domain name incase sensitive specification.

Description

As workaround, this PR will force the user defined hostname to lowercase with the .toLowerCase() method.

Testing

• cordova build
• cordova run

Also tested use cases where upper-case string could have been provided while we force lowercase.

Html

<a href="https://ABCDEFG/another-page.html">ANOTHER PAGE</a>

Javascript

window.location = "https://ABCDEFG/another-page.html";
