remove useless conditionals
`element` can never be a hash because:
1. `slice` returns a Parameters object and calls each on it: https://github.com/rails/rails/blob/cb3f25593b1137e344086364d4b1a52c08e8eb3b/actionpack/lib/action_controller/metal/strong_parameters.rb#L656
2. `each` which is implemented by `each_pair` will call `convert_hashes_to_parameters` on the value: https://github.com/rails/rails/blob/cb3f25593b1137e344086364d4b1a52c08e8eb3b/actionpack/lib/action_controller/metal/strong_parameters.rb#L192-197
3. `convert_hashes_to_parameters` will convert any hash objects in to parameters objects: https://github.com/rails/rails/blob/cb3f25593b1137e344086364d4b1a52c08e8eb3b/actionpack/lib/action_controller/metal/strong_parameters.rb#L550-566
