If SHCreateDirectoryExW is passed a non-null hWnd,
but the directory already exists,
ERROR_CANCELLED is returned in Wine,
rather than ERROR_ALREADY_EXISTS,
the Windows behaviour.
An application relying on an expected return code
may not proceed given the 0x4C7 1223 ERROR_CANCELLED,
rather than a 0xB7 183 ERROR_ALREADY_EXISTS
Warframe in-game screenshots (F6) demonstrates this behaviour

v2:
Add Test for conformance of SHCreateDirectoryExW with a Hwnd
when target directory already exists
v3:
Add missing newline on ok test hwnd fail string. Thanks Gijs
v4:
Made SHCreateDirectoryExW with Hwnd test already existing directory
fail string consistent with existing fail strings. Thanks Gijs
