Repro steps.

1. run ng g m my-module - [ will work as expected ]

2. decide that you want a module and routes, so run ng g m my-module --routing

3. get asked if you want to override the old module, hit y

4. get sad because the routing file was not created 😢

5. decide that you want to add a component matching the module name, so run ng g c my-module

6. get sad again because the new component got not added to your new my-module.module.ts but to your app.module.ts 😢

7. be happy again because the Angular CLI is such a timesaver for most parts 😄👍

The log given by the failure.

Mention any other details that might be useful.

Thanks to the team for all the effort ❤️
