Minor nits to cancellation error message (#921)

Minor nits to cancellation error message


Put the prompt name in quotes. Also specifying that we're resetting
outputs only, not the entire prompt or AIConfig. Also refreshed the
AIConfig to make sure that changes are propagated.

I also noticed that if you don't refresh the text lingers there. This
gets fixed automatically with the next PR in diff stack!
