logger: don't append std::endl to the message.

[luca-schlecker]

ILogHandler instances should take care of that:

class CustomLogger : public crow::ILogHandler {
 public:
  CustomLogger() {}
  void log(std::string message, crow::LogLevel /*level*/) {
    // "message" doesn't contain the timestamp and loglevel
    // prefix the default logger does and it doesn't end
    // in a newline.
    std::cerr << message << std::endl;
  }
};

I completely forgot about the newline at the start.. checking everything it seems to be a non issue, my bad.
