Fix std::basic_string printer with custom allocator

This fixes expansion of 'std::basic_string' in the locals
view when a custom allocator is used (which previously
would result in "<not accessible>" being shown);
for example, when expanding 's' at the breakpoint
in the following example:

    #include <string>

    template<class T>
    class myallocator : public std::allocator<T> {};

    int main()
    {
        std::basic_string<char, std::char_traits<char>, myallocator<char>> s("hello");
        return 0; // break here and expand value of 's' in locals view
    }
