Fix jsanitize in `contains_flow_or_job`

[gpetretto]

This change in emmet https://github.com/materialsproject/emmet/commit/7735bb1a51cd9b339789bbdca0df92fbe366ddb8 leads to an error in contains_flow_or_job, due to the impossibility to call as_dict on some Enums. This PR adds the enum_values=True to handle those cases.

In general, I am wondering if it is worth making this check every time a Flow is instantiated.

@gpetretto Fyi, I am trying to store the whole enum information in the output. I think this should fix this as well. Here are my pull requests: https://github.com/materialsvirtuallab/monty/pull/640 and https://github.com/materialsproject/jobflow/pull/565

What are your thoughts about this?
