rBac723db57fd8ba5 makes proper remapping of all pointers in Scene... including the object pointers of bases in ViewLayers. Using `BKE_main_collection_sync_remap()` makes sense here anyway (compared to `BKE_main_collection_sync()`, it additionally clears caches in ViewLayers and Collections), this whole code makes a lot of remapping. Note that I do not really understand *why* that was working OK before rBac723db57fd8ba5. I.E. *why* not remapping at all ViewLayers' base object pointers seemed to be OK... This whole collection/viewlayer caching is very hard to follow, and really needs a full rework at some point (just as much as ID copying code in general, and scene copying code in particular, in fact).
