Fix test suite by running select_image_for_pdf unconditionally
...
The purpose of this change that caused the problem was a minor
optimization for the tesseract renderer path that had it pull an image
from select_image_for_pdf so that it could use a JPEG instead of PNG,
instead of taking it from preprocess_clean where it would only get a PNG
and make large files.
