Fix file in try catch

If any fixer failed to fix sth - e.g. crush on some edge cases and try to access non-existing index of Tokens - then whole tool will crush.
After this it will only ignore that one file.

How do you think?

It would be great to also create a report for it to paste on gh issue - if this PR will meet positive reaction then I will create PR for reporting.
Maybe we should use `'S'` for skipped instead of `''`. That way people can actually see the skipping happening.
