bug: Cannot generate app-shell (Angular)

[intencje]

Bug Report

Ionic version:
[x] 5.x

Current behavior:
Command ng generate app-shell in "fresh" Ionic gives error:

Schematic input does not validate against the Schema: {}
Errors:

  Data path "" should have required property 'clientProject'.

Expected behavior:

User should be able to exec ng generate app-shell when he chose Angular during the generation of a new Ionic application

Mmm not even sure how you managed to get that far 😄

$ ng g app-shell
    Prerequisite for app shell is to define a router-outlet in your root component.

The built in app-shell schematic from angular doesn't appear to work out of the box with ionic since it looks for a router-outlet and not an ion-router-outlet.

A feature request could be made here to rework the app-shell schematic to support ionic apps.
A pull request would be greatly appreciated to any community member that wants to work on this!
