Fix NavigationObstacle2D/3D get_global_transform() error

Browse Source 
Fixes NavigationObstacle2D/3D reporting a 'get_global_transform: Condition "!is_inside_tree()" error when estimating the agent radius.

The collisionshapes that are lower in the SceneTree order than the obstacle node are not loaded in the SceneTree yet so the global_transform function fails.

Also adds warning message when this happens.
