Solving Ensemble problem requires ensemble algorithm (not the case for other ensemble solves)

[TorkelE]

E.g. this

opt_esol = solve(opt_eprob, Adam(5e-3); trajectories = n, maxiters = 10000)

yields a

ERROR: MethodError: no method matching __solve(::EnsembleProblem{…}, ::Adam{…}; trajectories::Int64, maxiters::Int64)
The function `__solve` exists, but no method is defined for this combination of argument types.

Closest candidates are:
  __solve(::SciMLBase.AbstractEnsembleProblem, ::A, ::SciMLBase.BasicEnsembleAlgorithm; trajectories, batch_size, progress_aggregate, pmap_batch_size, kwargs...) where A

while

opt_esol = solve(opt_eprob, Adam(5e-3), EnsembleThreads(); trajectories = n, maxiters = 10000)

works fine
