Application.php

<?

// Insert this before throw in getNamespace()
foreach ((array) data_get($composer, 'autoload-dev.psr-4') as $namespace => $path) {
  foreach ((array) $path as $pathChoice) {
    if (realpath(app_path()) == realpath(base_path().'/../'.$pathChoice)) {
      return $this->namespace = $namespace;
    }
  }
}
