Fix up ctrl+C handling in into_sqlite (#12130)

Browse Source 
I noticed that ctrl+C handling wasn't fully wired up in `into sqlite`,
for some data types we were ignoring ctrl+C presses.

I fixed that up and also made sure we roll back the current transaction
when cancelling (without that, I think we leak memory and database
locks).
