I tried to refractor email validation code to use the 
FILTER_VALIDATE_EMAIL filter instead of a regex. Our Unit tests failed, 
because it marked the following email addresses as invalid:

Reproduce code:

$wacky_but_valid_emails[] = '';
$wacky_but_valid_emails[] = 'a@com';

foreach( $wacky_but_valid_emails as $email ) {
        print "$email : ";
        $result = filter_var($email, FILTER_VALIDATE_EMAIL );


Expected result:
---------------- : bool(false)
a@com : bool(false)

Actual result:
-------------- : string(
a@com : string(a@com)
