[BUG] Fix Integration Test Warnings

[Mikefly123]

Short summary

We're using a few things in our integration test suite that are deprecated.

Steps to reproduce

Run make test-integration with a flight controller board or view the latest integration test logs.

Expected behavior

No warnings!

Actual behavior

We currently see 4 deprecation warnings when running the integration tests. This is not a critical issue, but should be addressed when someone has some time to cleanup our logs and stay current.
