[FIX] mass_mailing: company logo on unsubscribe url

Setup a multi-company account and multiple website (one for each
company), create a mail campaign from a different company than the
superuser, send the emails and unsubscribe, the company logo is the logo
of the company the superuser is in instead of the logo of the company
sending the email.
