[tor-commits] [orbot/master] Fixes VPN Request Cancel Bugs

    Fixes VPN Request Cancel Bugs
    
    - Cancelling the VPN Permission Request left the user on a blank screen. This happened on the main activity and in the onboarding flow
    - If on the main screen you enable VPN but then deny the permission, the switch was previously activiated despite VPN permissions being
      denied.
