    search-provider: renew inactivity timeout at each calculator run
    
    As per the async rewrite, now the daemon inactivity timeout might happen
    when another call has just been done, while we don't want this to be the case.
    
    So, everytime we do a subprocess call, let's renew the application timeout.
