Extend the code added in d6538246d3d (commit-graph: not compatible with replace objects, 2018-08-20) which ignored replace objects in the "write" command to ignore it in the "verify" command too. We can just move this assignment to the cmd_commit_graph(), it dispatches to "write" and "verify", and we're unlikely to ever get a sub-command that would like to consider replace refs. This will make tests added in eddc1f556cd (mktag tests: test update-ref and reachable fsck, 2021-06-17) pass in combination with the "GIT_TEST_COMMIT_GRAPH" mode added in 859fdc0c3cf (commit-graph: define GIT_TEST_COMMIT_GRAPH, 2018-08-29), except that mode is currently broken (but is being fixed concurrently).

OK. The only question I have is if this deserves some kind of a warning. If the user has replacement defined and makes an explicit request to work with the commit-graph, silently ignoring the request instead of telling them why we are ignoring may lead to confusion. Side note. It is a "question", not "objection". Other than that, nicely done. Thanks.
