[Fix #352] Do not register an offense for Rails/HttpPositionalArguments when given a splatted hash

[dvandersluis]

The following code will no longer register an offense:

[{ format: :json }, { format: :html }].each do |args|
  get :nothing, **args
end

Fixes #352.

I don't think this is necessary to include, it's not such a common approach.

[dvandersluis]

What about simplified to get :new, **options? I think that might be more straightforward?

@andyw8 I made the change I suggested, but if you still don't like it I'm happy to remove it!
