Demonstration code results in an error

[Checkpoint-89]

Description of the bug: the following code results in an error

from melusine.data import load_email_data
from melusine.pipeline import MelusinePipeline

# Load an email dataset
df = load_email_data()

# Load a pipeline
pipeline = MelusinePipeline.from_config("expeditor_pipeline")  

# Run the pipeline
df = pipeline.transform(df)

This is the same code as here but where "demo_pipeline" has been replaced by "expeditor_pipeline".

KeyError                                  Traceback (most recent call last)
