Remove excess allocation for kwsplat to kw call

Browse Source 
Previously, calls like the following duplicated the kwsplat hash
unnecessarily:

```ruby
def foo(a:) = a
hash = {a: 10}
foo(**hash)
```

This is due to the fix in ca204a20231. Since it targets when the callee
has no keyword parameters, skip duplicating when the method takes
keywords.
