Comment #1 on issue 2049 by asmeurer: Derivative(f(x), x).subs(f(x), y)
gives 0 instead of Derivative(y, x)

Chris found that this was introduced by commit fc0254fd870f1ad2f, from
issue 476. Strangely, the change, which is just to have
**{'evaluate':True} in Derivative._eval_subs(), kind of goes against the
spirit of the rest of that commit. So this one will be pretty easy to fix.
