operator: Vodafone: Fix VoWiFi emergency calling notification

Notifications are orginally identified by the notification manager by
tag and id, but commit 3f92e7b78d modifies this behavior by passing a
type id upon notifying instead. Cancelling a notification is still
attempted by tag and id though, which will obviously fail.

Fix this behavior by notifying by tag and id again.
