EspruinoHub crashes when gettingServices while writing from node-red

Ahh, sorry - just glanced at it quickly and saw uartService in there. Thanks! I'll merge that in then.

You'd have had to have manually submitted the file by Git - it's probably slightly easier if I do it but if you'd submitted it would have preserved your name as the committer for those lines of code. Since I'm dragging in everything it's not an issue though

edit: Sorry, there's no special debug command as far as I know
