Old description:

> Desired doctests:
> {{{

>                 sage: R._test_antipode()

>                 sage: s = SymmetricFunctions(QQ).schur()

New description:

 Desired doctests:
 {{{
                 sage: R = NonCommutativeSymmetricFunctions(QQ).ribbon()
                 sage: R._test_antipode()

             ::

                 sage: s = SymmetricFunctions(QQ).schur()
                 sage: s._test_antipode()
 }}}

 This would have caught the bug in #14160.
