Fix issue where restart would not properly display username if user was
not loaded.
Revert "Fix issue where restart would not properly display username if user was"

This reverts commit 7dbefd7463a9c580b04ff07d4123a1885a08641d.
UserIdCause.getUserName and UserCause.getUsername should both create a
user if the user does not exist.
Remove unnecessary parameter in method call. Also return "anonymous" if
User is null.
When userId is null then return anonymous, otherwise try to obtain the
display name.
