Function remove_finished_mutation_journal 

pub fn remove_finished_mutation_journal(
    analysis: &AnalysisOptions,
    report: &MutationReport,
) -> Result<bool, ProgrammaticError>

Removes the outcome journal of the project when report is complete, and returns true when it removed a journal. Call it after the report is saved: the saved report then holds each result. A partial or failed run keeps the journal, so --resume can continue it. A run that started no test runner (runner is absent) did not write or check the journal, so the journal can belong to an interrupted run of another scope, and it stays.

Errors

Returns an error when the config does not resolve or the journal cannot be removed.
