Bug 30838: Don't fallback through phone numbers for sms

This patch removes the fallback handling for smsalartnumber as the
to_address in notices. We ignore the to_address field in the message
queue at send time for sms anyway and use smsalertnumber exclusively so
having this field populated is just confusing to the end user
