Currently the sitelink's badge is kept when changing the sitelink. We should change this when making the edit on the repo. The badge should be kept when moving the site on the client.
The following should happen when a user changes the sitelink on the repo:
- he deletes the old sitelink in the text field and starts typing a new one
- the existing badges icon is turned into the placeholder icon that is also shown when no badge is set
- when pressing save the badge is removed in the database
