Ngrx Schematics: Generate container does not work properly, --help flag is broken.

[ ] Regression (a behavior that used to work and stopped working in a new release)

What is the current behavior?

ng g container feature --reducers reducers/index.ts
The option '--reducers' is not registered with the generate command. Run `ng generate --help` for a list of supported options.

ng g --help
TypeError: Cannot read property '0' of undefined

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-feature',
  templateUrl: './feature.component.html',
  styleUrls: ['./feature.component.css']
})
export class FeatureComponent implements OnInit {

  constructor(private store: Store<any>) { } }

  ngOnInit() {
  }

}

Expected behavior:

--reducers flag has to be registered with the generate command.
Also, generated component has to import Store from @ngrx/store.

Minimal reproduction of the problem with instructions:
