# What this PR does
This is a follow-up PR to https://github.com/grafana/oncall/pull/4628.
As @Ferril pointed out, there was a slight issue in
`apps.alerts.tasks.notify_user.perform_notification` method when using a
"fallback"/default user notification policy. This is because the
`log_record_pk` arg passed into `perform_notification` will fetch the
`UserNotificationPolicyLogRecord` object, but that object will have a
`notification_policy` set to `None` (because there's no persistent
`UserNotificationPolicy` object to refer to).
Instead we now pass in a second argument to `perform_notification`,
`use_default_notification_policy_fallback`. If this is true, simply grab
the transient/in-memory `UserNotificationPolicy` and use that inside of
this task
