Repro steps.

Was this an app that wasn't created using the CLI? What change did you do on your code? etc.

• Added baseUrl for relative imports
• Relative import in a component, e.g. import { TermsAndConditions} from 'app/termsandcondition'
• ng serve works fine.
• Adding i18n attribute and running ng-xi18n:
  $ ng-xi18n
  Error: Unexpected value 'TermsAndConditions' exported by the module 'SharedModule'
