The status page for an unconfigured training process loads forever

I clicked on this process referenced in #1197 (closed), but its workflow has expired. The process is still there, but has no workflow. A Workers process would just have caused a redirection to the worker process configuration page, since no workflow implies the process has not yet been started, but since a Training process is immediately started when it is created and never has a concept of an unconfigured state, nothing happens here. Instead, the process status just shows Loading tasks forever, and does not load anything since there is no workflow to load.

The page should state that this process has no tasks in this edge case.
