Arrays::renameKey() incorrect replacement for existing new keys.

[jmwebservices]

Version: 3.1

Bug Description

When $newKey exsits in $array and is positioned after $oldKey, Arrays::renameKey() preserves the value of $newKey over the value of $oldKey.

Steps To Reproduce

use Nette\Utils\Arrays;

$array  = [ 0 => 0, 1 => 1 ];
$oldKey = 0;
$newKey = 1;
$renamedArray = [ $newKey => $array[ $oldKey ] ];

Arrays::renameKey( $array, $oldKey, $newKey );

var_dump( $array === $renamedArray ); // bool(false)

Expected Behavior

bool(true)
