test(logging): pick this test's own records out of the shared log batch

The generic API logger batches whatever is queued when it flushes, so records
from tests in other files in the same job land in the same request. Two tests
assumed otherwise: one read actual_request[0], the other counted NDJSON lines,
and both broke whenever another file logged first. Select by the messages each
test sent instead, which keeps the format assertions and stops the order from
deciding the outcome.
