Provide default build settings for unit and ui test targets (tuist#501)

- The previous diff tuist#497 restructured the way the build settings were provided
- This sadly caused a regression of not providing default build settings for Unit/UI test bundles
- Those are now explictily added as product types
- Tests have been added to prevent future regressions

Test Plan:

- Verify the build settings match those provided by Xcode
