[IMP] mass_mailing : improve heuristics to handle seen mails

Currently the assumption is that if email field doesn't exist on the target
model the mail field has to be email_from. So if one model is targeted and
does not have a field email nor email_from the seen list will raise as it is
searching at least on email_from on the targeted model table.

Better heuristics implemented here is to apply the same rule as
'get email field' from MailThread.message_get_default_recipients§). It
searches for email_normalized (address mixin), email_from, partner_email
and email fields in addition to partner_id which covers all use cases in odoo.
