Subject: [PATCH 2/2] [Devicenotifications Engine] Keep at most one
 notification per UDI

Each notification is created as new datasource, and is newer removed
as long as the engine exists. This is especially bad for long living
applets like the device notifier.

Also cancel (remove source) any old notifications in case of a successful
setup, otherwise old error messages are shown in the device notifier.
