parse.y: Fix the locations of NODE in percent strings

  * parse.y (parser_yylex): token_flush before
    calling parse_string. Without token_flush
    the first locations of NODE in percent strings
    are set to the location of %.

  e.g. The locations of NODE_STR is fixed:

  ```
  %w[a b]
  ```

  * Before

  ```
  NODE_STR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 4) ("a")
  NODE_STR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 6) ("b")
  ```

  * After

  ```
  NODE_STR (line: 1, first_lineno: 1, first_column: 3, last_lineno: 1, last_column: 4) ("a")
  NODE_STR (line: 1, first_lineno: 1, first_column: 5, last_lineno: 1, last_column: 6) ("b")
  ```
