Fix T52415: Copy/Pasting a mesh immediately crashes blender

Since the paste object is pasted in the active collection, and not on
its original one, we need to flush/calculate the new collection base
settings (visibility, selectability, ...).

DEG_id_tag_update() for the scene now. Though it may be better to tag
only the object specific IDs in the future.
