Export: Invalid argument supplied for foreach

Hey people,

could you please fix it:

PHP Warning: Invalid argument supplied for foreach() in /wordpress/wp-content/plugins/woo-variation-gallery/includes/class-woo-variation-gallery-export-import.php on line 42

You have this part of code:

$gallery_images = get_post_meta( $product_id, 'woo_variation_gallery_images', true );
$images         = array();

foreach ( $gallery_images as $image_id ) {
  ...
}

But get_post_meta returns not always an array. It can be bool too 🙂

Therefore foreach (false as $image_id) => Warning!
