[inventory] Warning with host without configuration

[sanpii]

Q	A
Issue Type	Bug
Deployer Version	v6.1.0
Local Machine OS	Linux
Remote Machine OS	Linux

Description

After reading the code FileLoader::load(), I think this second foreach seems duplicated.

Steps to reproduce

Content of deploy.php

<?php declare(strict_types = 1);

namespace Deployer;

require 'recipe/common.php';

inventory('hosts.yml');

And a hosts.yml file contening:

host: ~

Output log

$ ./bin/dep config:hosts -vvv
