It is tedious to test all the overloads of QString::insert,
so get the help of the compiler to do it. The framework
was originally developed for testing append.
This change showed that the insert(int, QStringRef),
insert(int, const char*) and insert(int, QByteArray)
overloads were missing. They will be added in a separate
commit.
