The `{'infos': 'mail_sent'}` property returned by `action_send_mail()`
was apparently unused, and orginally intended for debugging, according
to its author.
Since previous commit adds a warning for such unknown properties,
removing it entirely keeps the testsuite green. And it's cleaner
than explicitly allowing that extra key, since it's unused.
