Position Tween Issue

[manuel465]

There is a fatal error in the Position Tween implementation when a new project is created.

To reproduce this issue follow these steps:

• Create a new Position Tween (Complete)
• Create a new project
• Create a new Tween
• Add a node to the Tween path
• Press Ctrl-Z (this command will restore the path of the first project)
• If you try to edit that path then the application crashes
