fix(@schematics/angular): remove empty scripts option value from new applications

The `scripts` option with an empty array value has been removed from newly
generated applications including with `ng new`. This option is less commonly
used and can be added if needed by a project. The removal reduces the total
size of the generated `angular.json`.
