    shell: update sidelist when active panel is set externally
    
    When the active panel is set by external agents, e.g. calling
    the Control Center through command line and asking to open a
    specific panel, the panel is correctly opened but the sidelist
    is not updated to reflect that.
    
    Fix that by selecting the externally set panel row, and eventually
    moving to the correct list.
