test: fix flaky ManualObservedGenerationIT by guarding null status

The status assertions could throw NPE on the first Awaitility poll before
the reconciler patched the status. untilAsserted retries AssertionErrors but
rethrows other exceptions immediately, so the NPE aborted the test instead of
retrying. Guard with assertThat(status).isNotNull() to keep polling.
