DartWorkerContext: Return the correct workerId(). (#17280) (#17306)

Browse Source 
Prior to this patch, the workerId() method did not actually return
the worker ID. It returned some other string that had similar information,
but was different.

This caused the /druid/dart-worker/workers API, to return an internal
server error. The API is useful for debugging, although it is not used
during actual queries.
