Problem/Motivation

Impossible to generate Controller

How to reproduce

1. run drupal gcon
2. enter module
3. Enter Controller class name

You will see the exception

It happens, that we pass a validator function to askEmpty, which doesn't have this parameter

Solution

No solutions for the moment, I need sometime to understand the logic of adding title. If someone can help or direct, it would be great.
From the first glance, it looks like we just need to remove validation function or use ask instead of askEmpty.

Version

Drupal Console 1.5.0
