When appending objects from an older file, versioning needs to run to add an auto smooth modifier if necessary. However, this was running for all objects rather than just the newly appended objects. It's quite wrong to modify existing objects here, so add an explicit check for that. This could improve performance as well, but skipping checks for objects when the work is unnecessary. The crash will hopefully be resolved by other improvements to the auto smooth versioning (making it properly idempotent and running it again should fix the problem with the hidden legacy flags still set). But I still think this PR is worth committing, to be very explicit about only modifying new objects in versioning code. Pull Request: https://projects.blender.org/blender/blender/pulls/119467
