Fix default parameter values for window.alert() / prompt() / confirm()

[Chris Dumez]

Fix default parameter values for window.alert() / prompt() / confirm() to match the specification:
- https://html.spec.whatwg.org/multipage/browsers.html#the-window-object

They should default to the empty string, not the string "undefined".

Firefox and chrome agree with the specification.

Looks like the GTK build failure is real.

Doesn't this break Objective-C bindings when alert is called without an argument?

We had this discussion on another bug already. optional has no impact on ObjC bindings, so no.

Okay. I didn't see your reply.  I guess someone else reviewed it?
