fix(@angular/cli): don't add leftovers when there are none

At the moment we are adding leftover args to `--` even when it's an empty array, this causes schematics without arguments to fail silently, because of https://github.com/angular/angular-cli/blob/07780b9272d985606d318da16d732dd28a41d592/packages/angular/cli/models/schematic-command.ts#L463 Fixes: #15156
