action “woocommerce_before_resend_order_emails” doesn’t pass 2nd parameter

Hello

You use
do_action( 'woocommerce_before_resend_order_emails', $order );
in file /includes/class-wcpdf-admin.php, line 628

But WooCommerce passes 2nd parameter ($email_type), for example,
do_action( 'woocommerce_before_resend_order_emails', $order, 'customer_invoice' );

You can check https://github.com/woocommerce/woocommerce/blob/master/includes/admin/meta-boxes/class-wc-meta-box-order-actions.php#L100

I have to report this bug as our plugin uses hook “woocommerce_before_resend_order_emails”.

Thanks, Alex
