We have different metrics for snapshot creation latency for full and diff snapshots (why? Good question), so if we're measuring diff snapshot creation latency we need to query diff_create_snapshot instead of full_create_snapshot.

Just inline this logic into the test instead of adding a property to SnapshotType because there is literally no other use of this pattern in our tests (if there ever will be, which I doubt, we can still abstract it away).
