Merge #16551: test: Test that low difficulty chain fork is rejected

333317ce6b test: Test that low difficulty chain fork is rejected (MarcoFalke)
fa31dc1bf4 test: Pass down correct chain name in tests (MarcoFalke)

Pull request description:

  To prevent OOM, Bitcoin Core will reject chain forks at low difficulty by default. This is the only use-case of checkpoints, so add a test for it to make sure the feature works as expected. If it didn't work, checkpoints would have no use-case and we might as well remove them
