Patch: subscription moderation problems

[Olivier Salaun - CRU <adresse@cachée>]

We've found a bug with subscribe.owner and subscribe.auth_owner scenarios of 
Sympa 3.4.3.
The scenario are using a new, sometimes undef, variable. When undef, this 
makes Sympa
always reject the right to subscribe to the list.

List.pm has been changed to be more tolerant.
Here is a patch against Sympa 3.4.3 :
