Implement copying of wxStringTokenizer correctly: compiler-generated versions didn't work as the position of the tokenizer didn't point into the correct string after making the copy. Fix this by adjusting the position iterator to use the copy of the string. Closes #16339. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@78050 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
