[PATCH v2] comdlg32/tests: Avoid test hang by changing current directory.

[Bernhard Übelacker]

Signed-off-by: Bernhard Übelacker 
----
For some reason this does not show up in the daily testbot runs,
but in single test runs after e.g. patch submissions.

v2:
- Removed changes to IFileDialogEvents_fnOnFolderChange.
- Removed some more lines remaining from debugging.
