tst_qfiledialog.exe completer -test assumes too much

If C:\ in windows has a folder called CMake, the (start at root) -test will fail, as the open dialog will get 3 entries instead of 2 when the test types 'C'.

This works in the CI, because there we have a folder called "C:\.cpanm", and the dot in front of the test makes the test behave differently.

So, I can make the test work for myself if I rename CMake to DMake or create a folder called .something. But I don't think, the test is supposed to work that way.
