Subject: [PATCH] Show the right size of placeholder image on single product
 page

in the template for the product image, wc_placeholder_img_src() returns the thumbnail size of the image.
In order to use 'woocommerce_single' as size, the function needs to be corrected, so the function use the size and not a calculated array of sizes.  wc_get_image_size doesn't return an height for the woocommerce_single size. Further and since the image sizes are declared, there is no need to translate the size to an array.
