store: Fix a mistake in how pruning status is reported

lutter · lutter · commit 97992cb852c2 · 2025-06-23T15:57:20.000-07:00
When we start copying nonfinal entities, we need to reset the start_vid and
next_vid. They don't necessarily have a direct connection to the same
values for nonfinal entities; e.g., it is possible that the start_vid for
nonfinal entities is smaller than the one for final entities.

This change only affects how we report the completion of prune operations;
it has no effect on what gets pruned and how.
