Empty Style Kit export isn't throwing an error as expected

[lushkant]

When exporting an empty Style Kit instead of throwing an error it gives this
{"success":true}

It's being caused in function handle_style_kit_export() at class-tools.php:355

There is no conditional check following up for this one when there is a wp_error wp_send_json_success();

Also the error throwing part can be personalized even further for users with this one right here - https://github.com/LucaRosaldi/wpfn-notifications
