tag: --force does not have to warn when creating tags
"git tag --force" mentions what old tag object is being replaced when it is used to update an existing tag, but it shows the same message when creating a new one. Stop doing that, as it does not add any information. Add a test for this and also to ensure --force can replace tags at all.
