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")
