Prevent to always create a run

[benoit-cty]

The ApiClient class is creating a run in init. But when we are using it only to get data it create useless entry in the database.

And now that the new API is in production, we could remove the warning.

Thanks @benoit-cty! Maybe we can remove the call to self._create_run() in the __init__? I see that we create the run anyhow if not present in the add_emissions See here/

Well, I think not having a run_id in add_emissions is more a workaround in case of a network error.

I prefer the explicit way of not asking to add a run.

Thanks @benoit-cty ! With this, the API client will be in better shape. I mentioned a minor comment
