During the development of this fix, I utilized the `test_full_yaml_log`
test, which is marked as slow. This test is excellent for reproducing
past job submissions. It can be executed using the following commands:
```
lavacli jobs logs --raw 12496073 > /tmp/log.yaml
pytest .gitlab-ci/tests/test_lava_job_submitter.py -m slow -s
```
Here, `12496073` is the LAVA job ID from this specific job:
https://gitlab.freedesktop.org/mesa/mesa/-/jobs/53546660
The logs were not functioning as expected due to a few mistakes I made
with generators, such as:
- Not reusing the `time_traveller_gen` generator to call `next` more
than once.
- Forgetting to parse the YAML inside `time_travel_from_log_chunk`.
Additionally:
- Added some statistics at the end of the test to aid in diagnosing
whether the test was reproduced accurately.
- Renamed some variables for clarity.
