Issue description

The AnimationTree state machine editor has different editing modes, a button which allows you to drag out transitions and a button which allows you to add new states by clicking. This editor will operate in a read-only mode when examining a tree with a resource embedded into another scene. However, when switching between an editable tree and a non-editable tree, the mode will be stuck on what it was previously.

Steps to reproduce

• Create a scene.
• Create an AnimationTree and give it a state machine.
• Save the scene.
• Create a new scene which inherits this scene.
• Add another local AnimationTree and state machine.
• In the editor for this node, click on the connect nodes button.
• Now click on the older AnimationTree from the inherited scene.
• Observe that the 'connect nodes' mode is still active even though it should be disallowed in this context.
