Nicholas Shahan c2a879e41d [tests] Cleanup .__proto__ use in native tests
The existing usage will no longer work as expected once the security
measures to prevent native Object prototype pollution are enabled.

The recommended replacements are `Object.getPrototypeOf()` and
`Object.setPrototypeOf()`.
