Subject: get_urls_from_pdf: Test extracted URLs

Add a test with a simple text-only PDF with three URLs.

Currently I'm getting the following failure, so visibly the order is not
necessarily the same as the visible order, and multi-line hyperlinks can
be encoded as two link areas:

    ---- tests::get_urls_from_pdf_extracts_urls_from_pdf stdout ----
