We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Make spawn_pipeline not depend on the order of tasks in the yaml file
Currently, if a task is defined in the yaml file before its dependencies, the spawn_pipeline script fails with:
```
Traceback (most recent call last):
  File "/code/spawn_pipeline.py", line 132, in <module>
    main()
  File "/code/spawn_pipeline.py", line 110, in main
    new_dependencies.append(id_mapping[dependency])
KeyError: 'regressor-finder'
```

So things like https://github.com/mozilla/bugbug/commit/aaa67b3b0a1db7530cbf88df644aff076fcd2e4e are needed.

We should make the spawn_pipeline script not depend on the order of definition of tasks in the yaml file.
