Remove "Stopped" logic from Phrequent workflows

Summary: We can remove this "Stopped" code as per feedback on D7327. I think having the full text of "In Progress" and "Suspended" is much clearer than just a '*' though, so I've only removed the ongoing check.

Test Plan: Ran a combination of arc start, arc stop and arc time and it all worked.
