Fixed "passing null to parameter" in Mage_Core_Helper_String

[kiatng]

Description (*)

I used https://onlinephp.io/ for testing. As an example:

$haystack = null;
$needle = null;
$offset = null;
$result = iconv_strpos($haystack, $needle, $offset, 'UTF-8');
var_dump($result);

produces

Deprecated: iconv_strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/user/scripts/code.php on line 5

Deprecated: iconv_strpos(): Passing null to parameter #2 ($needle) of type string is deprecated in /home/user/scripts/code.php on line 5

Deprecated: iconv_strpos(): Passing null to parameter #3 ($offset) of type int is deprecated in /home/user/scripts/code.php on line 5
bool(false)
