    extractor: Return when passphrase prompt was cancelled
    
    Currently, a misleading error appears when the passphrase prompt in Nautilus
    is cancelled. This is because the `scanned` signal is emitted regardless the
    `cancellable` state. This happens only for archives with one file. Let's
    return immediately to prevent this problematic behavior.
