fix crash in view culling where differentiator creates create instruction for existing view (facebook#51294)
Summary: Pull Request resolved: facebook#51294 changelog: [internal] Fix a crash where a node that is supposed to be culled doesn't get visited because culling context is not updated. The differentiator would generate a create instruction for a view that already exists. Stack trace for the crash: ``` * thread microsoft#1, queue = 'com.apple.main-thread', stop reason = signal SIGABRT * frame #0: 0x0000000111740874 libsystem_kernel.dylib`__pthread_kill + 8 frame
