Don't convert zero values to empty string 

PHP's empty() function returns true for 0, 0.00, "0.00" and other 0 variants.
That means woocommerce_process_shop_order_meta() will convert item meta with
a 0.00 or similar value to an empty string, which can break things that expect
a float or number. This commit fixes that.
