Exception malformed on HackedProjectWebDevDownloader

Lines 114-121 of HackedProjectWebDevDownloader.php throw an exception with an array as second parameter but the second parameter of the \Exception object is supposed to be the exception code, I think there's a t() call missing.

    // Throw an exception if it didn't work.
    if ($return_value != 0) {
      throw new \Exception('Could not clone project %project into path %path at branch %branch.', [
        '%project' => $this->project->title(),
        '%path' => $path,
        '%branch' => $branch,
      ]);
    }
