Fixes GB#621070: Re-enable volume cleanup

 * By default, all resources from volumes (removable or optical) which
   were NOT mounted in the last 3 days will be removed from the store
   when doing the stale volume check.

 * Stale volume check is done when tracker-miner-fs starts, and then
   scheduled to be done once a day.
