Repro Repo

This project was generated with Angular CLI version 7.2.1.

Repro Notes

• Start with an Angular Project v7
• Have a project structure that has a nested folder structure. i.e.

- Root/
    - angular.json
    - projects/
        - main-project/
            - dist/
            - tsconfig.json
            - src/
              - app
        - other-other-angular-project/
            - dist/
            - tsconfig.json    
            - src/
              - app

• Run update

ng update @angular/cli @angular/core

• Notice that in the projects/main-project/tsconfig.json, the module: x does not get updated to module: esnext which is required for the new dynamic import loading.
• Even if the tsconfig.json is not in the root of the project, the tsconfig.json is defined in angular.json
