Better sanity checking for finished downloads.
Downloads in the RUNNING state are considered ready to start so that
downloads are correctly resumed when the process crashes. However,
this causes a race condition while UpdateThread is processing a
Cursor when a DownloadThread finishes.
With this change, DownloadThread now skips requests for downloads
already marked as finished. Apps listening for the DOWNLOAD_COMPLETE
broadcast will no longer see data mutated by the second thread, and
will not see the broadcast duplicated.
