linting fails

Generated a new library and getting follewed linting errors:
```
Error: Error at playground/index.ts:9:31: Cannot find module 'testlib'.
Error at src/sample.component.spec.ts:7:1: Cannot find name 'describe'.
Error at src/sample.component.spec.ts:14:3: Cannot find name 'beforeEach'.
Error at src/sample.component.spec.ts:28:3: Cannot find name 'it'.
Error at src/sample.component.spec.ts:29:5: Cannot find name 'expect'.
```
After i changed the `tsconfig.json`
removed:
`"types": []`
added:
```
"typeRoots": [
"node_modules/@types"
]
```
I am still getting
`Error: Error at playground/index.ts:9:31: Cannot find module 'testlib'.`
