Add support for deleting mode inference results

May be worthwhile for each pipeline step to know how to cleanup after itself
let's start with this one and see how well it is used

- log any exceptions encountered during the analysis pipeline run
- Fix assert so that it prints meaningful error message
- remove pipeline results before testing the pipeline
- also copy the seed model over as part of testing
