Use actual raw line for ParserBot.recover_csv

[ghost]

@chorsley has a neat solution: https://github.com/chorsley/intelmq/blob/962d630bd2a3eb7991f905d5ab795835ff1e9725/intelmq/bots/parsers/zoneh/parser.py#L15

This way we do not need to reconstruct the raw line.

This code has been submitted in lib/bot.py via #1015.

@chorsley This adds the code to the zoneh parser, not to the common functions.

@wagner-certat given current time constraints, I'll need to come back to that later, unless someone beats me to it.

I'll move the code to the proper place in lib/ once the PR is merged. That involves many other adaptions too.
