First bug, was that the /registration/confirm had never attendee.
Because partner_ids was initialized with set() and so partner_ids &= set(xxx)
will be always empty.
Now the user have confirmation on screen that the registration is done...
Another bug/usuability problem was that when user register to a webinar
less than 1 hours before the event, if scheduler was not run menwhile,
the user has the link after that the webinar was starded...
Now, we force the mail to be send asap, and launch the scheduler at
each confirmation... Anyway, the list of email registration to send should be
never big, because every registration will launch the scheduler.
Test updated since the mail are sent direcly, it's normal to have 0 mail.
