fix(@schematics/angular): remove unnecessary scripts and dependencies

When new application is generated with --minimal flag it will be
created without any testing frameworks, linters, etc. But package.json
still contains broken scripts and dependencies.

So "test": "ng test", "lint": "ng lint" and "tslint": "~6.1.0",
"ts-node": "~8.3.0" should be removed. By analogy with "e2e": "ng e2e".

(cherry picked from commit 9975661)
