unreadVariable false positive when using iterators to change values in containers

[Steve Albright]

The code probably could be better but shows that values are changing in the container so the unreadVariable warning should not apply.

void Example(QMap<qstring, qobject*="">& moduleMap)
{
auto it = moduleMap.find("SomeKey");</qstring,>

if(it != moduleMap.end())
{
delete it.value();
it.value() = new QObject();
}
}
