Fix ExtName() function that is in common/file_utils.cc

  ExtName() function, which returns a file extension, was returning the wrong extention
  when there is '?' or '#' after a 'html' file path.

  (ex) If path is "file://abc.html?test=c", returned value was ".html?test=c".
       Now it is corrected to ".html"
