Ensure finishing of simulation of no match between job and resources can be guaranteed

[tfesenbecker]

Currently the simulation never finishes if there are jobs in the queue that can't be matched to any resource.
At least for the use case of static resources the simulation should finish once there are only jobs in the queue that can't be scheduled to any resources.

This is until now expected behaviour. If no sufficient resources are supplied, the simulation waits until they appear. You can still manage the simulation by defining a maximum length it should take. However, you could also ensure a preprocessing step to check if all jobs match at least one of the specified resources.
