unable to clear input field value when typing falsy value

[davidkwan95]

This is similar to the issue at #810

I am unable to clear the input field when putting an empty string or falsy value inside the type or insert method, although the documentation says

.type(selector[, text])  
Enters the text provided into the selector element.
Empty or falsey values provided for text will clear the selector's value.

This works:

nightmare
    .goto('http://google.com')
    .type('[name=q]','hi')
    .wait(1000)
    .type('[name=q]','')
    .wait(1000)
    .end()
    .then((result) => {
      console.log(result);
    })
