Fix "truncated header" in Details View with non-Oxygen styles

Browse source 
The code for painting the "empty header" was inconsistent with the
headers of the other columns, which is probably the reason why the other
styles got confused

a) No QStyleOptionHeader is used
b) Even if an empty header must be drawn, the last column is drawn with
   the option QStyleOptionHeader::End.

According to Christoph, it still doesn't work with the Skulpture style,
but it seems that the patch does at least not make things worse.
