Performance/Sample cop incorrectly autocorrects #shuffle[0, 3]

[tindron]

#shuffle[0, 3] is autocorrected to #sample instead of #sample(3).

Sorry about that. I didn't realize that shuffle could take in multiple arguments. I don't think this will be difficult to fix.

...On closer look, that isn't multiple arguments, it is an array selector on the end of shuffle. This can still be accounted for.

I have found a fix for #shuffle[0, 3]. I have been stuck on trying to fix shuffle(random: Random.new(1)). My big pain right now is that issue with random is causing me to have to rewrite the entire cop. Parsing of the node for #shuffle[0, 3] produces completely different results than #shuffle(random: Random.new(1)).
