li_std_wstring test rename to li_std_wstring_inherit

This testcase was only run in Ruby and Python and implements an
obscure feature where a C++ class inherits from a std::wstring.

The li_std_wstring test is left in place to be modified in next commit
for more regular wstring testing across all languages.
