Make "Ghost" not link to 404 page (#6410)

* Make Ghost not link to 404 page

* Make correct localization label show

* Create and use GetLastEventLabelFake for when a Ghost user has made the action, thus not linking to a user profile
* Add corresponding _fake entries to locale_en-US

* Make Ghost avatar not link to 404 page

* Make Ghost on milestone_issues not link to 404 page
