Description:
------------
When converting a DirectoryIterator instance into an array using
iterator_to_array, the array items appear to be converted to basic
DirectoryIterator instances with none of the file information intact.
The same does not appear to occur for other related classes
(FilesystemIterator, RecursiveDirectoryIterator).

Reproduce code:
---------------
<?php

echo "DirectoryIterator:\n";
$dit = new DirectoryIterator(dirname(__FILE__));
$ait = iterator_to_array($dit);
foreach ($ait as $file) {
	var_dump($file->getFilename());
}

echo "RecursiveDirectoryIterator:\n";
$rdit = new RecursiveDirectoryIterator(dirname(__FILE__));
$ait = iterator_to_array($rdit);
foreach ($ait as $file) {
	var_dump($file->getFilename());
}

?>

Expected result:
----------------
DirectoryIterator:
string(1) "."
string(2) ".."
string(7) "bug.php"
RecursiveDirectoryIterator:
string(7) "bug.php"


Actual result:
--------------
DirectoryIterator:
string(0) ""
string(0) ""
string(0) ""
RecursiveDirectoryIterator:
string(7) "bug.php"
