    Fix trivial bug in parsing bridge extra-info descriptors.
    
    If the first thing we'd learn from a bridge was an extra-info
    descriptor, we would not have stored the contained transports. This
    case is very unlikely and has very little effect. Worth fixing anyway.
    Found via code analysis.
