Ensure files get mediascanned after the download is completed.
Update file size in MediaStore to 0 before triggering mediascan
which should force MediaScanner to scan this file.
Also, add a clean-up job to trigger mediscan on already existing
downloads which should have been mediascanned but haven't and got
stuck in this state.
