test(network): [android] ResponseUtil unit tests (#48075)
Summary: Currently the class `ResponseUtil` is still in Java, I'm adding some unit tests so it is safer to migrate it to Kotlin. ## Changelog: [INTERNAL] - `ResponseUtil` unit tests Pull Request resolved: #48075 Test Plan: ```bash yarn test-android ``` Reviewed By: cortinico Differential Revision: D66727736 Pulled By: lunaleaps fbshipit-source-id: 9c89c75905b4e0c9c4820a556245a07e135e0f17
