#13538: AlgebraicExtensionFunctor should not make an assumption on the ordering
of
parameters

Currently, {{{AlgebraicExtensionFunctor}}} assumes that the
{{{.extension()}}} function of a field takes the generators' names as the
second argument. This is not always the case:
{{{
sage: K = Qp(3,3)
sage: R.<a> = K[]
sage: AEF = sage.categories.pushout.AlgebraicExtensionFunctor([a^2-3],
['a'], [None])
sage: AEF(K)
}}}
The attached patch resolves this problem.
