Spark AnalysisException in Model Exploration step 3

[riley-harper]

Running Model Exploration's step 3 "get feature importances" causes Spark to raise a pyspark.sql.utils.AnalysisException with the message "Table or view not found: model_eval_features_list". Somehow this step is expecting this table to exist when it doesn't. Maybe we should add this table to the step's required input tables and look at preceding steps to figure out where the disconnect is occurring.
