Codeception/AspectMock Parent class not found by locator
<p>I have a problem with <a href="https://github.com/Codeception/AspectMock" rel="noreferrer">Codeception/AspectMock</a>. 
When using custom autoloader and try to create an instance of a class which has parent form the same custom namespace I have this error: </p>

<blockquote>
  <p>PHP Fatal error:  Uncaught InvalidArgumentException: Class [parent
  class name] was not found by locator in
  vendor/goaop/parser-reflection/src/ReflectionEngine.php:112</p>
</blockquote>

<p>I have very simple setup:</p>

<pre><code>&lt;?php

require_once __DIR__ . '/vendor/autoload.php';

$kernel = AspectMock\Kernel::getInstance();
$kernel-&gt;init([
    'debug' =&gt; true,
    'includePaths' =&gt; [__DIR__. '/lib'],
]);
$kernel-&gt;loadFile(__DIR__ . '/autoload.php'); // custom autoloader

$b = new \lib\B();
</code></pre>

<p>Class \lib\B:</p>

<pre><code>namespace lib;

class B extends A {}
</code></pre>

<p>Class \lib\A:</p>

<pre><code>namespace lib;

class A
{
    public function getName()
    {
        return static::class;
    }
}
</code></pre>

<p>Class B is loaded via my custom autoloader, but then the locator tries to load parent class A via composer autoloader and returns this error. Is this a bug, or I'm doing something wrong? </p>
