DependencyChecker does not works with FileMock

[f3l1x]

I have had this code in my tests. It is failing with 2.4.0.

$loader = new ContainerLoader(TEMP_DIR);
$className = $loader->load(function (Compiler $compiler) {
    $compiler->loadConfig(FileMock::create('', 'neon'));
}, 'container');

Nette\InvalidStateException: Unexpected dependency boolean

I think its cause:

// Compiler.php

/**
 * Adds new configuration from file.
 * @return self
 */
public function loadConfig($file)
{
    $loader = new Config\Loader;
    $this->addConfig($loader->load($file));
    $this->dependencies->add($loader->getDependencies());
    return $this;
}

// Loader.php

/**
 * Reads configuration from file.
 * @param  string  file name
 * @param  string  optional section to load
 * @return array
 */
public function load($file, $section = NULL)
{
    if (!is_file($file) || !is_readable($file)) {
        throw new Nette\FileNotFoundException("File '$file' is missing or is not readable.");
    }
    $this->dependencies[] = realpath($file);
       ....
}

realpath(FileMock) == bool(FALSE)

It is maybe issue in nette/tester, but I'm not sure if it is issue at all. What do you think?
