Review Comment:
If the query throws before this line. What would happen? I would think the
`orElse` would be triggered:
```
val query = SparkConnectService.streamingSessionManager
.findCachedQuery(id, session) // Common case: query is cached in
connect session manager.
.orElse { // Else try to find it in active streams. Mostly will not be
found here.
Option(session.streams.get(id))
```
And that'd still return a query ID not found exception?
