Entering invalid text causes an error

[khodges42]

Echoing something like cat about will cause a str not found error.

My cheap fix was just to add a default to text, but there's probably a better way.

Terminal.prototype.type = function (text = "I can't let you do that, Tom.", callback) { this.typeSimulator.type(text, callback); };

Sorry for the waiting. I managed to fix it, I did some mistake on the if/else block.
Thank you for your observation.
