Hide the download summary on file open

Notifications can be dismissed with a
DownloadManager.ACTION_NOTIFICATION_CLICKED intent, which bypasses the
DownloadNotificationService so we don't get a chance to hide the
summary.  This adds a check to the
DownloadBroadcastReceiver#openDownload() path that allows us to hide any
dangling summary notifications that shouldn't be visible.  This also
lets us catch any clicks on the summary which gives us a chance to close
them out as well.
