Flaky tests due to network errors fetching properties

[joepio]

Sometimes when runnign cargo nextest run, I get errors like these:

thread 'db::test::index_invalidate_cache' panicked at 'called `Result::unwrap()` on an `Err` value: AtomicError { message: "Failed setting propval for 'https://localhost/agents/w0ppEskueRjKC6S9tAawjtFJYtTWsndcHpQ96OlHq6Q=' because property 'https://atomicdata.dev/properties/publicKey' could not be found. Failed getting property https://atomicdata.dev/properties/publicKey. Error when fetching https://atomicdata.dev/properties/publicKey : https://atomicdata.dev/properties/publicKey: Network Error: Network Error: Error encountered in the status line: timed out reading response", error_type: OtherError }', lib/src/db/test.rs:436:52

thread 'parse::test::serialize_parse_roundtrip' panicked at 'called `Result::unwrap()` on an `Err` value: AtomicError { message: "Unable to import JSON-AD. Unable to parse resource. Failed getting property https://atomicdata.dev/properties/name. Error when fetching https://atomicdata.dev/properties/name : https://atomicdata.dev/properties/name: Network Error: Network Error: Error encountered in a header: timed out reading response", error_type: OtherError }', lib/src/parse.rs:246:36

Edit: seems like the issue is that create_agent fetches properties, because they aren't loaded yet. This should not be needed, because we know the datatypes are valid.

I should find a way to make tests fail when they do a network call
