fix(meta): skip unnecessary delta persistence

What's changed and what's your intention?

During commit_epoch for newly created table, a GroupConstruct delta is expected, which triggers a false alarm. The alarm was added to assert only NewL0SubLevel delta was kept for time travel.

This PR resolves this issue by skipping delta contaning GroupConstruct for time travel, because for that delta a complete version snapshot is ensured to be created for time travel, based on should_mark_next_time_travel_version_snapshot. This redundant delta has never been used.
