Nested assets with preprocessing getting wrong extension

[waiting-for-dev]

Expected behavior

For a tree structure like:

| - my_assets/
|   - parent.css.scss
|   - nested/
|      - nested.css.scss

and a configuration file like:

require "hanami/assets"
require "sass"

Hanami::Assets.configure do
  sources << [
    "my_assets"
  ]
end

following output would be expected (omitting files with fingerprint):

- public/
-  assets/
-    parent.css
-    nested/
-      nested.css
- assets.json

Actual behavior

Instead, the following output is created:

- public/
-  assets/
-    parent.css
-    nested/
-      nested.css.scss # Notice the extension here.
- assets.json

Notice that the preprocessing happens, but the extension remains the same.

Steps to Reproduce the Problem

1. git clone https://github.com/waiting-for-dev/hanami_assets_nested_extensions_bug
2. cd hanami_assets_nested_extensions_bug
3. bundle
4. find my_assets -name "*"
5. bundle exec hanami-assets -c config.rb
6. find public -name "*"

@waiting-for-dev I'm sorry for taking so long to reply.

Using sassc fixes the problem:
