branch: delete obsolete message about changing branch of obsolete commit

We now rely on `rewriteutil.precheck()` to check for divergence, so we
don't need the extra check in `cmdutil.changebranch()`. The former
check is a little less strict in that it allows you to rewrite a
commit without non-obsolete successors.
