(GB/GBMR) (do not merge) delete file from disk when deleting from db
bug:3175143 sometimes mediaprovider doesn't delete the file from disk when it is deleted from its db. for example, audio files, pdf files. DownloadManager/DownloadApp should delete the file when it is deleted from downloads db. DO NOT MERGE this is esentially porting HC fix from DownloadService.java to GB Change-Id: I70f3a7ad968f82ccba00d664e9a2993d75a18d15
