Shipping Multiple Addresses for WooCommerce

There is a bug in this plugin due to phone now being a required field. In woocommerce-shipping-multiple-addresses/includes/class-wc-ms-address-book.php on line 46 the function get_user_default_address forgets to set the shipping_phone, so this will always fail the is_address_empty checks.

Adding the phone to the map field such as below appears to fix this:

‘shipping_phone’ => ‘phone’,

This plugin is completely unusable for me without this, due to phone being a required field.
