MDEV-10665: Json_writer produces extra members in output

Browse Source 
Fix an issue in Single_line_formatting_helper: flush_on_one_line()
didn't clean up the buffered items which could cause them to be
printed for the second time.

This can't be ever observed by a user (see MDEV text for details).
