"Showname" tickbox does not respect new messages in the IC log.

[collinxchu]

Describe the bug
When you untick "shownames" in the courtroom UI, shownames will revert to the folder's original name, but new messages will still have the custom name.

To reproduce
Have a player use a custom showname.
They send some messages. Untick "shownames".
Have them send more messages.
Marvel as the the IC log messages have their custom showname.

Expected behavior
Unticking "shownames" disables shownames -- including new ones in the IC log.
