ScriptingObject::CreateManagedInternal() tries to get Managed class name when there is no managed class assigned

Issue description:
ScriptingObject::CreateManagedInternal() checks for existence of Managed counterpart for given scripting object, if none is found it tries to print Warning message... here is the problem, it uses ToString() which gets it's name from Managed Class.
This results in Access Violation exception

Steps to reproduce:

• Create Visual Script
• Add GetKeyboard node

• none, see images
