I believe this is a missing AIP test. We want already deleted resources (including soft-deleted) return NotFound if another attempt to delete them is made.
If the user calling a soft Delete has proper permission, but the requested resource is already deleted, the service must succeed if allow_missing is true, and should error with NOT_FOUND (HTTP 404) if allow_missing is false.
In our case, we don't use allow_missing (can also be implicitly treated as its zero-value of false).
