From the Sherlock.Service.Master log. Just after a test completed and the VM was terminated.

The main problem seems to be in the fact that we don't check in the ActiveMachineEnvironment.State() if the IExecuteTestStepsCommands is still a valid reference and so we call it after (or during) the disconnection of the communication system.
