Describe the bug

After creating a new code-sharing project, ng serve results in an error and the demo is not shown.

From Angular CLI:

ERROR in ./src/polyfills.ts
Module not found: Error: Can't resolve 'core-js/es7/reflect' in 'C:\git\playground\hello-shared\src'

To Reproduce

1. Create new code-sharing project with ng new -c=@nativescript/schematics ns-demo --shared.
2. Run ng serve.

Expected behavior
Creating a new code-sharing project should include all files created in a new 10.1.0 Angular project (ng new). Notably, a .browserslistrc file was not created. Adding this file with the default content will resolve the issue:

# This file is used by the build system to adjust CSS and JS output to support the specified browsers below.
# For additional information regarding the format and rule options, please see:
# https://github.com/browserslist/browserslist#queries

# For the full list of supported browsers by the Angular framework, please see:
# https://angular.io/guide/browser-support

# You can see what browsers were selected by your queries by running:
#   npx browserslist

not IE 9-10 # Angular support for IE 9-10 has been deprecated and will be removed as of Angular v11. To opt-in, remove the 'not' prefix on this line.
not IE 11 # Angular supports IE 11 only as an opt-in. To opt-in, remove the 'not' prefix on this line.

Before Angular CLI used differential loading (see 1 and 2) a project dependency on core-js was necessary. The expected core-js was ~2.5.0, which provided different paths. The issue can alternatively be fixed by updating the default src/polyfills.ts file: replace import 'core-js/es7/reflect'; with import 'core-js/es/reflect';. This is less preferable than using differential loading by default.
