Bug introduced in 1400f64; that commit changed dmails so that
creator_ip_addr defaulted to CurrentUser.ip_addr like this:
after_initialize :initialize_attributes, if: :new_record?
def initialize_attributes
self.from_id ||= CurrentUser.id
self.creator_ip_addr ||= CurrentUser.ip_addr
end
...but creator_ip_addr already defaulted to 127.0.0.1 from the database,
so the ||= assignment didn't work. Remove the database default so we
always default to CurrentUser.ip_addr.
