    loleaflet: Exit early for invalid commandvalues
    
    LO core doesn't output any change tracking information for spreadsheets
    which results in sending an empty 'commandvalues: ' message to
    loleaflet. While the actual fix for it would go in LO core, lets handle
    this empty case for now in loleaflet, so that we don't throw any runtime
    JS exceptions.
