Laravel4 Connector: false assumption of 'db' existence

[Namek]

Method _after(TestCase $test) in codeception\src\Codeception\Module\Laravel4.php contains following lines:

if ($this->app['db'] && $this->cleanupDatabase()) {
    $this->app['db']->rollback();
}

My project does not use Database Service (Elastic Search in place) so I have disabled DatabaseServiceProvider in Laravel config. That's why it fails on if($this->app['db']) part. From debugging step by step I know that instead of calling offsetExists it immediately invokes offsetGet in Illuminate\Container\Container:

public function offsetGet($key)
{
    return $this->make($key);
}

What I get is ReflectionException - "Class db does not exist" from Container::build()

Same thing happens inside function _before(TestCase $test).

I'm not sure what triggers this error: this module, Laravel, PHP engine or quantum physics.

Issue is fixed by #3049 and #3048.
