cli: ensure first new HEAD is detached
The problem is that the first non-working-copy commit moves the unborn current branch to that commit, but jj doesn't "export" the moved branch. Therefore, the next jj invocation notices the "external" ref change, which was actually made by jj. I'm not sure why we play nice by setting the "current" HEAD, but I *think* it's okay to set the "new" HEAD and reset to the same commit to clear Git index.
