Can you fix all the remaining places where this warning is being raised in the same PR. This is the 3rd PR for the same change.

In current master this is the last place. I wanted to add this to the 2nd PR when it popped up, but took longer to figure out the proper way. Sorry.
That said, we also need to to watch out not to create new calls that raise this warning.
This fixes a commit from four days ago, 4f99a21#diff-7ee9dc74b44ac1e2c604f7bc0791475dR76, after the 2nd PR was submitted.
And 84b1fee#diff-90026976e5983729d8dcd51a360cf4aeR439, fixed in the 2nd PR was merged a week after the 1st PR on the same problem.

Thanks for looking on all the other places. Yeah, not sure how to avoid introducing this warning again since it only happen on Ruby 2.6 and that version is not even released yet. Maybe we can add a rubocop rule?

Why not just def find_template(finder, name, prefixes = [], partial = false, keys = [], options = {})?

@rafaelfranca will you accept PR with this change?

even find_template(finder, *args, **options) should be fine.

## Summary

This cop emulates the following Ruby warnings in Ruby 2.6.
ruby/ruby@a23eca2

```console
% ruby -we "def m(a) end; h = {foo: 1}; m(**h)"
-e:1: warning: passing splat keyword arguments as a single Hash to `m'
```

This cop does not have autocorrect because uses of splat keyword
arguments duplicates the argument hash instance.
So, it is not necessarily compatible code.

### Use splat keyword arguments (`foo(**h)`)

```console
% ruby -vwe "def m(a) p a.object_id; end; h = {k: :v}; p h.object_id; m(**h)"
ruby 2.6.0dev (2018-05-08 trunk 63359) [x86_64-darwin17]
70248917856620
-e:1: warning: passing splat keyword arguments as a single Hash to `m'
70248917856460
```

### Use non-splat keyword arguments (`foo(h)`)

```console
% ruby -vwe "def m(a) p a.object_id; end; h = {k: :v}; p h.object_id; m(h)"
ruby 2.6.0dev (2018-05-08 trunk 63359) [x86_64-darwin17]
