Fix string iteration logic in wxFTP::Pwd()

Browse Source 
wxString iterators can't be dereferenced once they reach the end of the
string, so compare them with end rather than checking if the value they point
to is non-NUL.

This makes wxFTP::Pwd() actually work, which was apparently broken since quite
some time (perhaps ever since c9f7896861 9+
years ago).

Closes #17679.
