REVISION SUMMARY
  When a download is canceled, finishes, or is interrupted (e.g. loss of network connection) we finish the `KJob` to remove it from notification area.
  However, when a job was interrupted and is then resumed, the download ID is reused by the browser and we only get sent updates for a job we no longer have.
  When we get a change event from `interrupted` to `in_progress` just pretend a new download was created and carry on as normal.
  
  BUG: 401038

TEST PLAN
  - Started a download, cut my network, waited for it to fail, resumed it: now got a download job in notification area, previously nothing would happen
  - Canceling and restarting the download still works fine
  - Starting a new download still works fine

REPOSITORY
  R856 Plasma Browser Integration
