Adding Values after call to clear() fails.

[VicKrawciw]

Describe the bug
Adding Values after call to clear() fails.

To Reproduce
Steps to reproduce the behavior:
1.
bool result = false;

Json::Value root;
Json::Reader reader;

result = reader.parse(request, request + strlen(request), root, false);
if (result)
{
std::string command;
int advanced;
try
{
command = root[0]["command"].asString();
advanced = root[0]["advanced"].asInt();

  //Done with command
  root.clear();

  if (command.compare("GetStationDesc") == 0)
  {
   // If we use the root above after clear() this addition fails.
    // Json::Value root;
    root["name"] = "S2000Test";
    root["type"] = "S2000";

Expected behavior
After the root.clear() I should be able to add items.
