REVISION SUMMARY
  When explicitly refreshing the view (e.g. F5 <https://phabricator.kde.org/F5>) also refresh disk space info.
  This would also allow us to raise the refresh interval somewhat.
  
  CCBUG: 398612

TEST PLAN
  Hit F5 <https://phabricator.kde.org/F5>, had it refresh the info right away
