### Issue description

**Current behavior:**

While executing npm test, okta service fails with injector error.

**Expected behavior:**

It should not fail, it should have injecton

**Steps to reproduce:**

**1. At component level**
Imports:
`import { anyServiceWithOkta } from '../services/anyServiceWithOkta.service';`

**2. AnyServiceWithOkta service file**
```
import { OktaAuth } from '@okta/okta-auth-js';
import { OKTA_CONFIG } from '@okta/okta-angular';

constructor(@Inject(OKTA_AUTH) private oktaAuth: OktaAuth, private http: HttpClient) { }
```

**3. AnyServiceWithOkta Spec file for testing**
```
import { CustomerService } from './customer.service';
import { OktaAuth } from '@okta/okta-auth-js';
import { OKTA_CONFIG } from '@okta/okta-angular';

describe('CustomerService', () => {
const oktaConfig = {
issuer: 'issuerlink',
clientId: 'client-id',
redirectUri: 'http://localhost:4200/callback'
};
const oktaAuth = new OktaAuth(oktaConfig);

beforeEach(() => TestBed.configureTestingModule({
imports: [ ],
providers: [{provide: OKTA_CONFIG, useValue: { oktaAuth },
useClass: MockAuthorizationService
}]
}));
```

**Error at service level:**
```

```

Main issue is to run test case with Okta with in service file. Means service is accessing
```
import { OktaAuth } from '@okta/okta-auth-js';
import { OKTA_CONFIG } from '@okta/okta-angular';

```
with okta config, creating okta instance in service.

Thanks, and Regards
