Unhandled 400 error when trying to stop a running job

Sentry Issue: ARKINDEX-FRONTEND-89T

Error: Request failed with status code 400
  at createError (./node_modules/axios/lib/core/createError.js:16:15)

I believe this has happened due to the frontend showing the job as pending while it was actually already running.

Maybe the frontend could, before it tries to delete a job, refresh the job list and check that the job is actually still removable. Also, despite error handling in the store, this issue is still sent to Sentry.
