Summary:
changelog: [internal]
Attempt at fixing a crash in `Scheduler::uiManagerDidCloneShadowNode` by setting delegate to nullptr explicitly.
I don't think this will make a difference because `scheduler_` is released at the end of `dealloc` but it is worth a shot. Maybe some complex interaction between Obj-C and C++ comes into play here.
In this diff I also removed `_animationDriver = nullptr` because dealloc will do that automatically.
