Bug 37967: Allow auto renewals notices to be sent via phone

Auto renewals via phone are only disallowed because itiva did not support them.
There is no reason to disallow auto-reneals for the generic phone transport.
Twilio, for example, would have no problem sending those phone notices.

Test Plan:
1) Apply this patch
2) Run updatedatabase.pl
3) Note you can now select phone for auto-renewals!
