Harry YuandFacebook GitHub Bot ee1a191cb1 Avoid crash by handling missing views in dispatchViewManagerCommand (#33795)
Summary:
Based on Google Play crash logs, crashes due to the assertions in `dispatchViewManagerCommand` is our top source of crashes:

```
com.facebook.react.uimanager.IllegalViewOperationException: Unable to execute operation dispatchViewManagerCommand: blur on view with tag: 17549, since the view does not exists
        at com.facebook.react.uimanager.UIImplementation.assertViewExists(UIImplementation.java:830)
        at com.facebook.react.uimanager.UIImplementation.dispatchViewManagerCommand(UIImplementation.java:713)
        at com.facebook.react.uimanager.UIManagerModule.dispatchCommand(UIManagerModule.java:739)
        at com.facebook.react.uimanager.UIManagerModule.dispatchViewManagerCommand(UIManagerModule.java:726)
        at com.facebook.react.uimanager.ReanimatedUIManager.dispatchViewManagerCommand(ReanimatedUIManager.java:233)
        at java.lang.reflect.Method.invoke(Method.java:-2)
        at com.facebook.react.bridge.JavaMethodWrapper.invoke(JavaMethodWrapper.java:372)
        at com.facebook.react.bridge.JavaModuleWrapper.invoke(JavaModuleWrapper.java:151)
        at com.facebook.react.bridge.queue.NativeRunnable.run(NativeRunnable.java:-2)
```

There are many other places in UIImplementation that instead of throwing a fatal exception, just log a message and continues execution.

Logging a message and discarding the command should be safe for commands like "blur this view". We keep the previous behavior in debug mode, but just log and discard commands in production.
