Fix default extension behavior with GetOpenFileName

[mehmet yasar]

Hi,

If a default extension was given, Wine could not open files without
extension. Now it works better, for example with default extension "txt" :

If you type "filename", we will try first "filename.txt" and then
"filename" if the previous doesn't exist.

TODO :
If you type "filename" (with quotes) and there is "filename" and
"filename.txt" in the same directory, we should open "filename".
(The same logic applies when selecting file on listview with mouse)

Changelog:
          Fix default extension behavior with GetOpenFileName
