Nodes with batch category stuck in ready status

Currently, CLI-session evaluation of models that involve nodes with batch category (resource annotations) is not working properly. Evaluation of nodes with interactive category has no problem. However when evaluating batch-type nodes, these are stuck in READY status, and are never queued to the batch system. The issue occurrs for either nodes evaluating purely via Python, or using other external programs/modules.

Have to test whether this problem is also present in CLI-script evaluation. It is likely that this problem is also present.
