Add the default baseHref value to angular.json

• Issue introduced by [Issue 145] Support base path #1642

Description

If you run yarn run start:dev you'll see that the baseHref in your config is automatically added to angular.json. As a result angular.json almost always have a change when you commit.

This PR adds the default baseHref of / to angular.json to ensure that change only occurs when you use a custom nameSpace in your dev config.

👍 Looks good to me too. Also tested in prod mode and verified that subpaths still work (i.e. #1642)
