Create canonical demoAdapters for testing (#735)

PluginAdapters and Node/Edge types are increasingly fundamental to the
cred explorer. Prior to this commit, we had no canonical demo
adapters/types, and we would create ad-hoc and messy adapters whenever
we needed them. This creates unnecessary repetition and lowers test
quality.

This commit creates a canonical demo adapter (loosely themed based on
the wonderful game [Factorio]) and refactors most existing test cases to
use the demo adapters. In particular, the horrible mess of pagerankTable
adapters has been removed.

[Factorio]: https://www.factorio.com/

I left `aggregate.test.js` untouched because I would have needed to
materially re-write the tests to port them over. I added a comment so
that if we ever do re-write those tests, we'll use the new demo
adapters.

Test plan: `yarn test` passes.
