Create new method commit_graph_compatible(r) to check if a given repository r is compatible with the commit-graph feature. Fill the method with a check to see if replace-objects exist. Test this interaction succeeds, including ignoring an existing commit-graph and failing to write a new commit-graph. However, we do ensure that we write a new commit-graph by setting read_replace_refs to 0, thereby ignoring the replace refs.
