fix(FA parser): search terms undefined in FA 5.9

An issue with the FA 5.9 metadata was causing the script to exit because
the search terms couldn't be found because for 2 of the new icons. The
search terms where moved from search.terms to the top level. Issue was
raised with FA https://github.com/FortAwesome/Font-Awesome-Pro/issues/1380

Closes #16
