parse.y: Change the last location of none

• parse.y: Change the last location of none to be
  equal to the first location of none.
  Sometimes none has length (parser->tokp does not
  match lex_p when none is generated).
  This leads to invalid code_ranges.

  e.g. The locations of the NODE_CALL (:sort) is fixed:

  x.sort.join(" ") 

  • Before

  NODE_CALL (line: 1, code_range: (1,0)-(1,7)) 

  • After

  NODE_CALL (line: 1, code_range: (1,0)-(1,6))
