Validate params before request

[pcothenet]

What

• Validates body parameters before making the HTTP requests

Why

• See this PR for details

Notes

• Add new flights parameters #41 should be reviewed and merged first (this is built on top)
• This is less interesting for node than for ruby (the class generation does not throw an error if a parameter is not accepted, it just gets rid of it)

SDK Release Checklist

• Have you added an integration test for the changes?
• Have you built the package locally and made queries against it successfully?
• Did you update the changelog?
• Did you bump the package version?
• For breaking changes, did you plan for the release of the new SDK versions and deploy the API to production?

was this causing any issues or is this just a style preference?

[pcothenet]

Good question. Automatic setting from prettier in the pre-commit hook. Not sure why it didn't update when I made the change initially

@kleinjm I bit the bullet and rewrote this test in the same style as the Ruby one.
