commit-graph: test --split across alternate without --split
We allow sharing commit-graph files across alternates. When we are
writing a split commit-graph, we allow adding tip graph files that
are not in the alternate, but include commits from our local repo.
However, if our alternate is not using the split commit-graph format,
its file is at .git/objects/info/commit-graph and we are trying to
write files in .git/objects/info/commit-graphs/graph-{hash}.graph.
We already have logic to ensure we do not merge across alternate
boundaries, but we also cannot have a commit-graph chain to our
alternate if uses the old filename structure.
Create a test that verifies we create a new split commit-graph
with only one level and we do not modify the existing commit-graph
in the alternate.
