Bug 4461: Use KohaAdminEmailAddress pref as 'from'

Bug 4461: Use KohaAdminEmailAddress pref as 'from'

We usually do not specify the from_address on enqueuing the notice, but
when sending it (from _send_message_by_email). That way a) the code is
centralized (as we must use $patron->notice_email_address) and b) the
email used is the one that is in the DB when the letter is effectively
sent.
Here I guess you need to give it when the notice is enqueued as you want
to default to the koha admin address.

I do not think it's a good idea, we should not send an email with "from"
if not really sent by the user.
We have the borrowernumber anyway to know who filled the form.
