Check if array index exists before using it 

WC_Geolite_Integration::get_country_iso() sometimes returns null instead of an array, so this commit adds a check to account for that possibility before using the returned value. Doing this to prevent the following undefined index notice:

PHP Notice: Undefined index: country in wp-content/plugins/woocommerce/includes/class-wc-geolite-integration.php on line 60

Fixes #20594
