Enable system users for comment.LoadPoster (#28014)

Browse source 
System users (Ghost, ActionsUser, etc) have a negative id and may be the
author of a comment, either because it was created by a now deleted user
or via an action using a transient token.

The GetPossibleUserByID function has special cases related to system
users and will not fail if given a negative id.
