fix the orientation combobox in the print dialog

Changing the orientation value to anything else than 'Automatic'
didn't do anything by default. This was because by default
neither isPaperSizeFromUser() nor getPapersizeFromSetup()
were set, so PrintDialog::setPaperOrientation() did nothing.
It looks to me like 8cbdc6a068ad88fc43a98bd0f88 that introduced it
was rather broken (not just this bug, but also e.g. the ugly
modifying of the paper sizes by non-const reference from a const
function). In fact this whole stuff still looks broken to me, why
does it change paper size instead of just setting the orientation?
It seems like the orientation gets reset, or maybe the setting
was just a band-aid. I don't know how to fix that all though.
