SpiceDB: LookupSubjects may return partial results if a specific kind of relation is used
### Background Use of a relation of the form: `relation folder: folder | folder#parent` with an arrow such as `folder->view` can cause LookupSubjects to only return the subjects found under subjects for *either* `folder` or `folder#parent`. This bug *only* manifests if the *same* subject type is used multiple types in a relation, relationships exist for both subject types *and* an arrow is used over the relation. ### Impact Any user making a negative authorization decision based on the results of a LookupSubjects request with version before v1.30.1 is affected. ### Workarounds Avoid using LookupSubjects for negative authorization decisions and/or avoid using the broken schema.
