Description:
------------
After calling RecursiveDirectoryIterator::getChildren(), RecursiveDirectoryIterator::seek(0) has no effect.

Test script:
---------------
<?php

mkdir(__DIR__.'/temp');
mkdir(__DIR__.'/temp/a');
mkdir(__DIR__.'/temp/b');

$iterator = new \RecursiveDirectoryIterator(__DIR__.'/temp', \RecursiveDirectoryIterator::SKIP_DOTS);

$iterator->seek(0);
var_dump($iterator->key());

$iterator->seek(1);
var_dump($iterator->key());

$iterator->getChildren();

$iterator->seek(0);
var_dump($iterator->key());

$iterator->seek(1);
var_dump($iterator->key());

rmdir(__DIR__.'/temp/a');
rmdir(__DIR__.'/temp/b');
rmdir(__DIR__.'/temp');


Expected result:
----------------
string(7) "<snip>/temp/b"
string(7) "<snip>/temp/a"
string(7) "<snip>/temp/b"
string(7) "<snip>/temp/a"

Actual result:
--------------
string(7) "<snip>/temp/b"
string(7) "<snip>/temp/a"
string(7) "<snip>/temp/a"
string(7) "<snip>/temp/a"

I did some more testing. The same bugs appears for DirectoryIterator:

---------------
<?php

mkdir(__DIR__.'/temp');
mkdir(__DIR__.'/temp/a');
mkdir(__DIR__.'/temp/b');

$iterator = new DirectoryIterator(__DIR__.'/temp');

$iterator->seek(0);
var_dump($iterator->current()->getPathname());

$iterator->seek(1);
var_dump($iterator->current()->getPathname());

$iterator->seek(0);
var_dump($iterator->current()->getPathname());

$iterator->seek(1);
var_dump($iterator->current()->getPathname());

rmdir(__DIR__.'/temp/a');
rmdir(__DIR__.'/temp/b');
rmdir(__DIR__.'/temp');
---------------

Neither rewind() nor seek(0) works.
