[FIX] mail: mailing domain not set properly

When selecting contacts from Contacts list views and clicking on
action window "Partner Mass Mailing", the 'active_domain' must be
filled in the wizard with the selecting contacts. In this way,
the right mailing_domain will be set when creating the related
mail.mass_mailing record (in addons/mass_mailing/wizard/mail_compose_message.py
in function get_mail_values).
