If we create an internal link in a richtext field, pointing to a location that is later removed, the internal link is still present when we edit the object again. It would be nice to have these "dead" links automatically cleaned

Steps to reproduce

-Create one article1
-Create folder "Folder1" and in rich text field, create a link to "article1"
-remove article1
-View "Folder1" - ok, the link is not present
-Edit "Folder1"
-We can see that the link reference to deleted "article1" is still present. If we try to publish it again without doing anything else, we have the notification error "An error occurred while publishing the draft" and the response with

{"ErrorMessage":{"_media-type":"application\/vnd.ez.api.ErrorMessage+json","errorCode":404,"errorMessage":"Not Found","errorDescription":"Could not find 'location' with identifier '54'"}}
