create run_name for get_call http route if not specified (#1182)

We're not setting a `run_name` on the `get_call` endpoint. This comes up when [calling a function via CURL](https://github.com/run-house/runhouse/actions/runs/10487756209/job/29048800796).

This update creates a run name if not provided in the request
