Flaky test caused by resource fetching

[joepio]

E.g. here

 fetching body of https://atomicdata.dev/properties/name
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: AtomicError { message: "Failed getting property https://atomicdata.dev/properties/name. Error when fetching https://atomicdata.dev/properties/name : https://atomicdata.dev/properties/name: Connection Failed: tls connection init failed: Resource temporarily unavailable (os error 11)", error_type: OtherError }', lib/src/parse.rs:274:59
failures:
    parse::test::parse_nested_resource_map_roundtrip

For some reason the default store wasn't loaded here. I think it's a good idea to do this by default when initializing a Store. Or maybe use a test helper function that always does this.
