Remove `pipeline.any_report_artifact_for_type` method
any_report_artifact_for_type
is used exclusively in Pipeline Presenter
The pipeline has an alternative method to fetch reports batch_lookup_report_artifact_for_file_type
We should use it since:
- It improves performance: it reduces SQL calls and loads all reports in memory.
- We'll unify the way we fetch reports in different features.
