Fix disabling Remote Access (#17880)
Fixes #17873
Summary of the issue:
Disabling Remote Access would fail, causing the settings GUI to stop working, and settings to be saved incorrectly.
Description of user facing changes
Disabling Remote Access now works properly.
Description of development approach
Fixed the remoteClient.menu.Menu.terminate method.
This was still trying to clear connectItem and disconnectItem, even those were unified into connectionItem in #17825.
I thought I had fixed this issue in that PR, but evidently the changes got lost somewhere along the way 😅
