Andreas Haas 1620f46f03 Viewport: Fix undefined behaviour found by llvm sanitizer. 
When godot was running as the project manager, it tried to call a method on a null pointer (get_tree()->get_edited_scene_root()).
This is undefined behaviour and caused a crash when compiled with sanitizing enabled.
