refactor: Generalize log ownership to allow for scratch jobs (#182)

* refactor: Generalize log ownership to allow for scratch jobs

Importing may fail when creating a project. We don't want to lose this output,
but we don't want to allow users to create a failing project.

This generalizes logs to soon enable one-off situations where a user can upload
their archive, create a project, and watch the output parse to completion.

* Improve file table schema by using hash

* Fix racey test by allowing logs before

* Add debug logging for PostgreSQL insert
