confirm-method in Vagrantfile ignores return value of ask(...) call.

[pixell]

Confirm method in Vagrantfile does not work as expected. This is because the return value of ask method call is ignored here: https://github.com/Seravo/wordpress/blob/master/Vagrantfile#L292. So it always fallbacks to default value.
