Remove a cache invalidation which would cause the shared index to be rewritten on as-is commits. When the cache-tree has changed, we need to update it. But we don't necessarily need to update the shared index. So setting active_cache_changed to SOMETHING_CHANGED is unnecessary. Instead, we let update_main_cache_tree just update the CACHE_TREE_CHANGED bit. In order to test this, make test-dump-split-index not segfault on missing replace_bitmap/delete_bitmap. This new codepath is not called now that the test passes, but is necessary to avoid a segfault when the new test is run with the old builtin/commit.c code.
