title: Angular http client interceptors not known in lazy loaded feature module
body: <p>We have made an interceptor in Angular. This one is exported with a forRoot() in a core module. The app module imports this core module with forRoot().</p>
  
  <p>In the lazy loaded feature module the interceptor is not known.</p>
  
  <p>How can we fix this problem?</p>
  
  <p>The http client module is imported only once in the app module.</p>
