  --- 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.
