OptimisticLockException on worker node can cause jobs to be stuck in DISPATCHING state

Steps to reproduce

Steps to reproduce:
1. Run an Opencast cluster with significant load
2. Observe in Jobs table that some jobs remain in DISPATCHING state
3. Observe in Servers table that some servers have jobs queued but aren't running any jobs

Workaround by restarting worker node (after placing it in maintenance mode).

This only seems to affect Inspect jobs (not sure why).
