Fix INPUT_MODULE ordering

[cwschilly]

We get this error on the deploy docs pipeline:

Traceback (most recent call last):
  File "python.py", line 3208, in <module>
    run(os.path.dirname(os.path.abspath(args.conf)), config, templates=os.path.abspath(args.templates))
  File "python.py", line 2986, in run
    modules_to_crawl += crawl_module(state, path, object)
  File "python.py", line 653, in crawl_module
    assert parent_path_str in state.name_map, "%s listed in INPUT_MODULES without %s being known yet, add the parent explicitly earlier" % ('.'.join(path), parent_path_str)
AssertionError: lbaf.Model.lbsAffineCombinationWorkModel listed in INPUT_MODULES without lbaf.Model being known yet, add the parent explicitly earlier

We should also try to find a way to get these errors to show up on the PR instead of waiting until we merge to uncover them (since the deploy_docs pipeline only completes on pushes to develop or main).
