Remove - Universal Analytics integration

[tomalec]

I found an issue that when you add (in a snippet or another extension) another script that has a dependency on woocommerce-google-analytics-integration and enqueue it not in the footer, for some reason the inline script with wcgaiData is not rendered, breaking the functionality.

Steps to reproduce

1. Add a snippet:

add_action( 'wp_enqueue_scripts', function () {
    wp_register_script( 'my-code', '', array('woocommerce-google-analytics-integration'), null, false );
    wp_add_inline_script( 'my-code', "console.log('Hello');" );
    wp_enqueue_script( 'my-code' );
} );
