D8007: popplerextractor: don't try to guess the title if there isn't one.

  Just wanted to chime in to say how my workflow <https://xkcd.com/1172/> depended on this bit of code.
  
  I compiled the `tests/dump.cpp` tool and used it as a CLI PDF metadata dumper.
  
  I then wrote this script <https://github.com/dufferzafar/.scripts/blob/master/pdf-titles> which renames a PDF file according to its title.
  
  I use this script to batch rename research papers I download and it works pretty well.
  
  This removal doesn't really affect me and is probably for the better.
