Fix for #1147 (#1651)

* fixes #1147

Previously, the manipulator would stop and stuck on a disk when it isn't empty, but also cannot be emptied any more (network is full). This fixes this: If the network cannot accept any items anymore, the disk will be moved to output.

* Update CHANGELOG.md

* removed testing leftovers

* changed behaviour
