Redirect to the status for run 0 on newly created processes

Closes #1196 (closed)

This changes all the redirections to the process-status route that occur right after some API call that causes a Process to be started. When this happens, there should only be one first run, run 0, so we can redirect to run 0 directly instead of using the automatic last run detection.

This might reduce the amount of cancelled route events on ARKINDEX-FRONTEND-AVH. Note that most of those events are benign, as those are just redirections that happen at a time that just causes Vue Router to see them as an error, even though there is nothing wrong.
