Translate objects recursively when key points to object in translations

fix for #946

Motivation: I want to be able to use the translate pipe in combination with the *ngFor keyword in my angular components

With this Pull Request the following now works...

translations.json

{
  OBJECT: {
    TEST: 'this is a test {{key}}',
    ANOTHER_TEST: 'this is another test {{key}}'
  }
}

any view

<ul>
  <li *ngFor="let translation of 'OBJECT' | translate: { key: 'value' } | keyvalue">{ translation.value }</li>
</ul>

result

<ul>
  <li>this is a test value</li>
  <li>this is another test value</li>
</ul>

previously the interpolation would fail, resulting in

<ul>
  <li>this is a test {{key}}</li>
  <li>this is another test {{key}}</li>
</ul>
