[FIX] sms: send SMS on transfer without traceback

Steps to reproduce:
- Create a SMS template with the 'Applies to' property set to
  Transfer (without this the action will never appear)
- Go to Transfer, pick one, open action and try to send a SMS

Issue:
Traceback

Cause:
When sending the SMS we try to modify the 'mobile' attribute of
'stock.picking' but it doesn't exist.
