IDN email validation broken

[Anton]

@danielkerr, latest changes broke IDN emails validation again.

filter_var($email, FILTER_VALIDATE_EMAIL) will never pass validation without punycoding email domain names.

opencart/upload/system/helper/validation.php

Line 35 in d17ffff

 //$email = $local . '@' . idn_to_ascii($domain, IDNA_NONTRANSITIONAL_TO_ASCII, INTL_IDNA_VARIANT_UTS46); 

opencart/upload/system/helper/validation.php

Line 37 in d17ffff

 return filter_var($email, FILTER_VALIDATE_EMAIL); 

#13597
