Let Hash#slice return a Hash
In order to keep this method compatible with the Ruby 2.5 version of Hash#slice.
This bahavior is actually slightly incompatibile with previous versions of Active Support
but it might not cause a real problem, since HWIA, the biggest use case of Hash subclassing here,
already overrides `slice` to return another HWIA.
