trajectory_follower_nodes test is flaky
Description
A breakout issue from #1031 (closed) that addresses the failures in trajectory_follower_nodes
There has been a number of jobs that fail in the same way recently. Just to name a few:
- https://gitlab.com/autowarefoundation/autoware.auto/AutowareAuto/-/jobs/1570424961
- https://gitlab.com/autowarefoundation/autoware.auto/AutowareAuto/-/jobs/1587629857
From the error message:
[ RUN ] FakeNodeFixture.set_param_smoke_test
>>>
build/trajectory_follower_nodes/test_results/trajectory_follower_nodes/test_trajectory_follower_nodes.gtest.xml: 1 test, 1 error, 0 failures, 0 skipped
- trajectory_follower_nodes test_trajectory_follower_nodes.gtest.missing_result
<<< error message
The test did not generate a result file.
>>>
it seems that the smoke test hangs.
Expected behavior
The test should consistently pass the CI pipeline.
