fputcsv(): escape must be a character when exporting orders

[jerome2710]

Description

When trying to export orders from the element-index, fputcsv fails as $this->escapeChar is an empty string.

yii\base\ErrorException: fputcsv(): escape must be a character
craftcms/commerce#8 /xxx/vendor/craftcms/cms/src/web/CsvResponseFormatter.php(103): yii\base\ErrorHandler::handleError
craftcms/commerce#7 /xxx/vendor/craftcms/cms/src/web/ErrorHandler.php(84): craft\web\ErrorHandler::handleError

craftcms/commerce#1 /xxx/vendor/yiisoft/yii2/base/Application.php(398): yii\base\Application::run
#0 /index.php(40): null

Steps to reproduce

1. Navigate to /admin/commerce/orders
2. Use the export function in the bottom right corner (I'm using raw data in CSV)
