Modified getUserById

This change allows getUserById to load a blocked user if needed.
The page Admin->Users->List All Users requires this as new users are blocked.

This will fix a bug where new users aren't listed and the last active user is repeated in the list.
Added missing space.

Further testing revealed I had left out a space.
