uxtheme: let OpenThemeData() always keep the window theme sane

[Frank Richter]

OpenThemeData() now always sets the window theme to the handle returned
(even if that is NULL) - previously, it could happen that when no theme
was active or the theme data could not be opened that the window theme
remained became then-dangling (and hence subsequent calls to
GetWindowTheme() would return that bogus theme).
