Re-enable CI tests (#1760)

This re-enables CI tests on every PR 🎉.
This uses make test-integration, which runs tests sequentially.

In theory, we also have test-integration-parallel but it seems to be very flaky: many tests randomly timeout. I didn't spend too much time investigating this, it's probably worth its own investigation in a separate PR, but for now it's important to re-enable CI tests, even if they are a bit slower.
