org-export-babel-evaluate=nil ignores ":exports results" setting - this has changed

[Derek Feichtinger <derek.feichtinger@psi.ch>]

When org-export-babel-evaluate is set to nil, I see a different behavior 
now as compared to earlier versions of org.

Now it seems that all header arguments of a code block are ignored, 
including the arguments to the :exports setting. Even when I have set 
":exports results" or ":exports code" I always get code and results 
exported in the resulting document. If org-export-babel-evaluate is set 
to t then everything behaves the way I was used to, ":exports results" 
just exports the results and when set to "code" just the code is exported.

I think that this should be considered a bug. I frequently (even most of 
the time) want to evaluate the org blocks manually, not upon export, but 
I want to be able to define whether only the results should be visible 
in the exported document. For generated pictures this is usually the 
normal case.

I am using org 9.0.5 from MELPA now, and I can't completely say when 
this changed, but I am very sure that a few weeks ago the behavior was 
different, since I am using org a lot for preparing documents.

Simple test document:
