Zhisheng Huang 6311bbcfb4 Fix the visibleObjects inconsistency assertion ... Summary: Another source-of-truth inconsistency issue. I kept getting this assertion T65423827 task. It turned out the the root cause is that we use the `_viewSectionControllerMap` to keep track of the mapping between view and section controller. Which is dangerous. Because the UICV's source of truth is the `sectionMap`, now we are adding another source of truth between view <-> sectionController to be `_viewSectionControllerMap`, this is just waiting for bugs to happen. We should always refers to sectionMap as the source of truth for everything here: since we can get the section index, we can replace all the `-sectionControllerForView` to use `-sectionControllerForSection:` instead, which is safer. Multiple source of truth is the bug for this unexpected assertion. Once we can cleanup this, then we dont need to use that weird: `- (void)mapView:(UICollectionReusableView *)view toSectionController:(IGListSectionController *)sectionController` API which we might forget to map, that can cause bug.
