[regression] missing [constVariableReference] when iterating a std::map

[Leander Schulten]

Given the following code

std::map<std::sting, std::vector<std::string>> map;
void test(){
    for(const auto &entry : map){
        auto& names = entry.second;
        for(auto &name : names) {
            std::cout << name << std::endl;
        }
    }
}

I got

example_const_ref.cpp:5:19: style: Variable 'name' can be declared as reference to const [constVariableReference]
        for(auto &name : names) {
                  ^

before https://github.com/danmar/cppcheck/commit/6fc4d3624ba47de14f59244ec5fe9e5550f68309
but with this commit the warning is not reported anymore (which is wrong).
