Delivery endpoint API does not update the path for links in richTextFiled when assets are moved

Steps to reproduce

1.  Start Magnolia
2.  Upload asset via Assets App inside some folder e.g. test
3. Create a new page with provided LM e.g. test
4. In rich text filed link the asset
5. Call endpoint for newly created page: http://localhost:8080/magnoliaAuthor/.rest/delivery/pages/test
6. See that link in rich text is: <a href=\"${link:{uuid: {d784c4c4-c0cb-479b-a56b-ee2933b9657c}

   ,repository:

   {dam}

   ,path:

   {/test/Screenshot-2021-05-26-at-08.41.png}

   }}\">Screenshot-2021-05-26-at-08.41.png</a>
   So path is: /test/Screenshot-2021-05-26-at-08.41.png

7. Go to Asset App and move the asset to different place
8. Call again endpoint http://localhost:8080/magnoliaAuthor/.rest/delivery/pages/test
9. Returned path in REST is still /test/Screenshot-2021-05-26-at-08.41.png

Expected results

The path returned in ${link...} should be updated to the new placement of the asset

Actual results

The old path is returned

Workaround
