Conflict with basic auth plugin and woocommerce api

Hi,

Could you please change one line in your code?
In pixelyoursite/facebook-pixel-master.php line 27
From:
add_action( 'plugins_loaded', 'pys_free_init' );

To:
add_action( 'wp_loaded', 'pys_free_init' );

This fixes a fatal error when using the woocommerce api in combination with the basic auth for the wp-api plugin. It has to do with that $wp_rewrite is not ready before after wp has loaded.
