Title: rerun for #251 (fix for fat arrow positives

I also encountered issue #249. @Sinetheta fix works fine for me. Here's a hopefully working pull request.
(only for the missinng_fat_arrow_rule)

As `containsButIsnt` aborts as soon as it finds a class node, I am not sure whether this really covers all special cases. However all tests run fine.
