ensure we're passing through api keys and key types from notifications

when we made the change to async persist notifications, we forgot to
pass through api_key_id and key_type. in send_sms/email, for legacy
reasons, they default to None/KEY_TYPE_NORMAL, so regardless of what
your api key was set up as, we would send real messages!

TODO: Once the PaaS transition is complete and the task changes are
reverted, remove the api_key_id and key_type params from the send_*
tasks entirely, as those are only called from the csv job flow, and
don't need them
