double check styling action hook

[lukasjuhas]

From Wordpress Support:

esemlabel (@esemlabel) Maybe the line in public function __construct(), that adds red background to admin_menu_bar button, should be added in ‘admin_bar_menu’ hook, because background is missing at frontend when mm is enabled.

add_action('admin_head', array( $this, 'style' ));

//change to add_action('admin_bar_menu', array( $this, 'style' ));
