Workaround: Run the following SQL:

DECLARE @OldId UNIQUEIDENTIFIER
SET @OldId  = (SELECT pkID FROM tblScheduledItem WHERE TypeName = 'EPiServer.Notification.NotificationDispatcherJob')
IF NOT @OldId IS NULL
BEGIN
PRINT 'Removing duplicate'
DELETE FROM tblScheduledItemLog WHERE fkScheduledItemId = @OldId
DELETE FROM tblScheduledItem WHERE pkID = @OldId
END
