Invalid tsconfig.app.json after generating web worker

[christianlundberg]

🐞 Bug report

Command (mark with an x)

- [ ] new
- [ ] build
- [ ] serve
- [ ] test
- [ ] e2e
- [x ] generate
- [ ] add
- [ ] update
- [ ] lint
- [ ] xi18n
- [ ] run
- [ ] config
- [ ] help
- [ ] version
- [ ] doc

Is this a regression?

Angular only began official support of web workers so I guess not.

Description

After running ng g web-worker sheet --project=enterprise, the tsconfig.app.json looks like this:

{
    "extends": "./tsconfig.json",
    "compilerOptions": {
        "outDir": "../../dist/out-tsc",
        "types": []
    },
    "exclude": ["src/test.ts", "**/*.spec.ts",]    "src/**/*.worker.ts"
,
    "include": ["**/*.ts"]
}

Notice "src/**/*.worker.ts" was placed outside of the exclude array. This causes plenty of errors upon building the app which is how I discovered the error.
