I encountered a situation where Drupal needed revision link for the field collection item entity.

Drupal\Core\Entity\Exception\UndefinedLinkTemplateException: No link template 'revision' found for the 'field_collection_item' entity type in Drupal\Core\Entity\Entity->toUrl() (line 214 of core/lib/Drupal/Core/Entity/Entity.php).

This error only occured when viewing an node revision which is not the default revision. (e.g. in combination with workbench_moderation)

See the patch file for my solution of the problem. I just needed to add the revision link on the field collection item entity and rename the route.
