Feedback form use 'undefined'

[tigerfoot]

Since a few time (but nothing is clear when it appear exactly) if a user send a feedback form without one of the field filled, undefined is used as value and not as state. So in From field for example we got email coming with undefined@myhost.mytld in place of the defined configuration email

Seen with python 3.4 and python 3.6 pyramid 1.9.1

It look like self.get_param('email', None) return undefined (the value found in json form) in string format instead of real Undefine or None.
