Move semantic for GetObject changed

[tirolerstefan]

I have tested latest master commit e4bde97 against release 1.1.0 commit f54b0e4.
It looks like GetObject with assignment doesn't move, but copy data, now.

Here is my minimal code snippet:

#include <iostream>
#include <string>

#include "rapidjson/document.h"
#include "rapidjson/rapidjson.h"


int main (void)
{
    std::string strJson = "{"
                           "\"name\": \"Chuck Norris\","
                           "\"bestfriend\": "
                              "{"
                                  "\"name\": \"Jean Claude\""
                              "}"
                       "}";
    
    rapidjson::Document d;
    rapidjson::ParseResult res = d.Parse(strJson.data());
    
    if (d.HasMember("bestfriend") && d["bestfriend"].IsObject())
        {
        // move semantic !! d["bestfriend"] will become null in v1.1.0.
        const rapidjson::Value& bestfriend  = d["bestfriend"].GetObject();
        
        std::cout << "ObjectEmpty? " << (d["bestfriend"].ObjectEmpty()?"yes":"no") << std::endl;
        }

    return 0;
}

Build line
g++ -g -std=c++11 -o rj -I../rapidjson_repo/include main.cpp

Output with commit f54b0e4 (v1.1.0):
ObjectEmpty? yes

Output with commit e4bde97:
ObjectEmpty? no

Using git bisect, I got commit cbf62de as first "bad" commit:

cbf62de55d684b70df2ae072097568719454f321 is the first bad commit

Was this change in behaviour intended?
Thanks for your help!

@slsyy - maybe you have an idea, too (referring #1404). Thanks!
