Bugfix

- YaraFileProcessor.__replace_for_each_one_to_many() did not handle lines with only spaces or tabs well. Since the non_white_space_index only got set higher then 0 if a non_white_space character
was found likes without spaces or tabs would double in size.
- Added a check, if non_white_space_index == 0 then set it to the lenghth of the line.
