Title: Fixed a bug with last command repeating in debugger

Debugger usually repeat it's last command if user submits an empty line. Unfortunately, this functionality depends on a bug that got fixed in joyent/node@9126dd2d903f3cf842f0c11a8349d794dde68e98 .

PS: Repl has history only if output is a terminal. So I see no way to test it using automated scripts.
