Hi, I noticed an unexpected behavior with a localized boolean field.

A quick example:

class Person
include Mongoid::Document
field :active, type: Boolean, localize: true, default: false
end

me = Person.new
me.active?

1. returns true instead of false

This happens here: https://github.com/mongoid/mongoid/blob/master/lib/mongoid/fields.rb#L453

I will try to send a PR but not sure I'll have time in the next weeks for that.
Best,

Did
