Call handleUpdateLayout even if the content didn't change 

Summary:
This PR fixes #11096.

I don't know enough the ReactAndroid's source code so I don't know if this is correct but I hope it is.

In a recent commit (d4b8ae7a8a), the `dispatchUpdates` method now returns a boolean to dispatch or not the `onLayout` event. This works well but if the content is unchanged, the line `nativeViewHierarchyOptimizer.handleUpdateLayout(this);` is never called. I don't know if it was intended but it was this which introduces my issue. I called this again even if the content didn't change. This was the behaviour before 0.38 so I guess I didn't break anything.

**Test plan (required)**

I tested my pretty big app with this fix and every screen is ok.
