Ichthyostega 606669aa1b Scheduler: further investigation but no solution for the emergency-trigger
Last summer, I already identified a problmatic aspect
which could cause the Scheduler to fall idle without further notice:
5b62438eb4

Basically this situation should raise a **Scheduler-Emergency**,
but the only location where it can be easily detected is way down
in the implementation and has currently no clean way of signalling.
Moreover, how to handle a Scheduler-Emergency is likewise an open
question, an will in turn require even more cross-cutting notifications
and trigger actions somewhere at Render-Engine top-level.

By marking the location where this problem could be detected,
inadvertently I broke the SchedulerCommutator_test, which of course
must execute precisely this logic and check for the proper result.

Yet the problem as such is tricky and possibly far-reaching;
notably when processing long-running render jobs will reliably trigger
this situation — unless we establish additional dedicated control-logic
especially to cope with long-running jobs (opened #1382 for this topic)

__Bottom line__: we are far from addressing any of these issues right now,
and thus I reduced that failure to a warning message, so that at least
`SchedulerCommutator_test` passes again (it's not actually a defect there)
