[GUI/Psychology] Running new scenario with default settings causes attributes not found exception

Summary

Creating a new scenario and running it with default settings leads to attributes not found exception.

Current bug behavior?

Running the new scenario causes

• AttributesNotFoundException: org.vadere.state.attributes.models.psychology.perception.AttributesSimplePerceptionModel
• AttributesNotFoundException: org.vadere.state.attributes.models.psychology.perception.AttributesSimplePerceptionModel

This occurs because the attributes are not defined.

Correct behavior?

Running a new scenario should be possible with default settings (given that a source and a corresponding target are created). That is, an exception should be raised neither for SimplePerceptionModel nor for SimpleCognitionModel.

Steps to reproduce

Open the GUI, create a new scenario, load OSM as the locomotion model, (define source and corresponding target) and run the scenario.

Starting point

Add missing attributes by default to json node scenario.psychologyLayer.attributesModel.
