fpb-lint check lists alphabetical order of non alphabetical language pages

[tt512]

Hi!

I guess fpb-lint doesn't check alphabetical order of lists because ja is not included in langsToAlphabetize and dictionary order of Japanese is not alphabetical also. However fpb-lint checks alphabetical order on Japanese document.

/home/tat/free-programming-books/free-programming-books-ja.md
  4:3-17:80  warning  Alphabetical ordering: swap l.17 and l.16  alphabetize-lists  remark-lint
  4:3-17:80  warning  Alphabetical ordering: swap l.11 and l.10  alphabetize-lists  remark-lint

⚠ 2 warnings

In addition, I found out alphabetize-lists plugin appended increasingly to preset.plugin list in forEach loop by inserting log for debugging.

     processor.process(doc, (err, file) => {
       if (report(err || file) !== 'no issues found') {

output:

I think it's not expected behavior, so I'll create PR.
