Adjoints don't work with Zygote if we use default alg

[prbzrg]

Minimal Reproducible Example 👇

using DifferentialEquations, SciMLSensitivity, Zygote

function f(u, p, t)
    sum(p) * u
end

r = rand(Float32, 8, 64)
ps = rand(Float32, 16)
ts = (0.0f0, 1.0f0)

function f2(x)
    prob = ODEProblem(f, r, ts, x)
    sol = solve(prob; sensealg = InterpolatingAdjoint(; autojacvec = ZygoteVJP()))
    sum(last(sol.u))
end

f2(ps)
Zygote.gradient(f2, ps)

I suggest updating the test to use OrdinaryDiffEqDefault instead. When we have a default algorithm, we should test against it.
There is

but it isn't trying every combination of sensealg to see whether they work.
