cmd/geth: Ctrl-C in combination with js causes unclean shutdown

[rustyx]

System information

Geth version: 1.8.3-stable
OS & Version: Windows 10 x64

Expected behaviour

Clean shutdown when pressing Ctrl-C while a script is running.

Actual behaviour

Unclean shutdown.

Steps to reproduce the behaviour

1. Create a file test.js with the following contents:
   eth.filter("latest", function() {});
2. Start geth js test.js
3. Once started, press Ctrl+C.
4. Geth is killed instead of gracefully shutting down.

Sorry, that bot can be over-eager sometimes.

Fwiw, I cannot repro this on linux on master (works as it should)

Just tested with 1.8.27 on Windows, the issue is still there. With geth --preload test.js all is fine, but with geth js test.js Ctrl-C causes immediate termination/unclean shutdown.

Perhaps it's a windows only thing? @FrankSzendzielarz can you try this out?
