Downloadable product and custom uploads directory

Hi, I have a problem with downloadable products.

When you try to download a purchased file, it redirects you to the file path under woocommerce_uploads and the .htaccess does its job and forbids the access.

My uploads directory is outside wordpress, in http://mysite.local/app/uploads/ and wordpress core is in http://mysite.local/wp/

I think there is something to do in WC_Download_Handler class (woocommerce\includes\class-wc-download-handler.php), at line 170.

To fix this until then, I just put this code into a php file :

add_filter('woocommerce_product_file_download_path', function($file_path, $this, $download_id) {
  return str_replace( WP_CONTENT_URL, WP_CONTENT_DIR, $file_path );
}, 99, 3);

I hope this will help some people.
