typo first->second
[Console] Avoided an unnecessary check.

It only makes sense to do the second check if the --no-interaction
option was not passed.

Running posix_isatty() raises a warning with some stream types (like MEMORY).
With this patch, warning could be avoided by passing the --no-interaction option.
