Tax.js loading by default

Once Pro Sites plugin is enabled, you'll notice tax.js file is enqueued by default in the frontend homepage, like:

<script type='text/javascript' src='http://websiteURL.com/wp-content/plugins/pro-sites/pro-sites-files/js/tax.js?ver=3.5.7'></script>

The Tax Settings aren't enabled in Pro Sites plugin, and the above files shouldn't be enqueued by default.
