HarmonyOS react-native-view-shot使用

尝试将harmony/react_native_openharmony/src/main/cpp/RNOH/CppComponentInstance.h中的：

protected:
  std::string getIdFromProps(
  facebook::react::SharedViewProps const& props) const {
  if (props->testId != "") {
  return props->testId;
} else if (props->nativeId != "") {
  return props->nativeId;
} else {
  std::ostringstream id;
  id << ShadowNodeT::Name() << "@" << m_tag;
  return id.str();
}
}

修改为：

protected:
  std::string getIdFromProps(
  facebook::react::SharedViewProps const& props) const {
  std::ostringstream id;
  id << m_tag;
  return id.str();
}
