    app: don't use the user context in GimpDeviceEditor's container view
    
    GimpDeviceInfo is a GimpToolPreset now, and using the user context
    would cause the device info selected in the dialog to be set globally
    as tool preset. Use a temporary context instead, the container view
    just needs it because.
