    relaylist: remove assertions that fail measurement
    
    When the descriptor or network status of a relay was not obtained,
    some attributes can't be obtained it can be return None instead
    of failing the measurement.
    Also, there's no need for hasattr when getattr can just return
    None as default.
    
    Closes #28870. Bugfix v0.4.0
