query --print_query behavior is confusing

[cmungall]

• --print-query does not print, but instead writes to dosdp.out
• If --print-query true, then --outfile file is silently ignored and there is no match tsv results.
  • This can be confusing if I say --outfile foo.tsv and there is an old copy of foo.tsv corresponding to different arguments
  • Ideally options would be monotonic or compose in intuitive ways
