Fix a false positive for Rails/RedundantActiveRecordAllMethod

Resolves #1114 (comment)

This PR fixes a false positive for `Rails/RedundantActiveRecordAllMethod`
when using some `Enumerable`'s methods with block argument.

`Enumerable#find` and `ActiveRecord::Base#find` have different arguments,
So false positives can be prevented.
