Title: Fixed the lack of a sender attribute for Message object

I got an error below when I try to make a user enabled "Send password registration link".

pyramid_mailer.exceptions.InvalidMessage
InvalidMessage: No sender address has been set

According to pyramid_mailer validation, the Message object needs a sender attribute.
