JSON array goes wrong on interactive mode

[KEINOS]

As of v2.6.0, the brackets come before interaction and miss the last token like so.

Note the [ bracket place and first token element of "私は鰻".

The last token, "うち" with the ID 8027 of the previous sentence "すもももももももものうち" appears.

The expected behavior may be as below.

This is my bad, sorry. Here's the fix and I will PR it A.S.A.P.

func printTokensInJSON(s *bufio.Scanner, t *tokenizer.Tokenizer, mode tokenizer.TokenizeMode) (err error) {
	var buff []byte

-	fmtPrintF("[\n") // Begin array bracket

	for s.Scan() {
+		fmtPrintF("[\n") // Begin array bracket

		sen := s.Text()
		tokens := t.Analyze(sen, mode)

		for _, tok := range tokens {
			if tok.ID == tokenizer.BosEosID {
				continue
			}

			if len(buff) > 0 {
				fmtPrintF("%s,\n", buff) // Print array element (JSON with comma)
			}

			if buff, err = parseTokenToJSON(tok); err != nil {
				return err
			}
		}

+		fmtPrintF("%s\n", buff) // Spit out the last buffer without comma to close the array
+		fmtPrintF("]\n")        // End array bracket
	}

-	if s.Err() == nil {
-		fmtPrintF("%s\n", buff) // Spit out the last buffer without comma to close the array
-		fmtPrintF("]\n")        // End array bracket

	return s.Err()
