Activate test for survival aorsf

[AnnaNzrv]

Description

Currently single and feat_all autotests are deactivated.

Reproducible example

test_that("autotest", {
  set.seed(1) # there was presumable a weird bug
  learner = lrn("surv.aorsf")
  expect_learner(learner)
  # for some reason the feat_all test randomly stopped working, check later if the
  # problem goes away (could not reproduce locally)
  result = run_autotest(learner,
    exclude = "single || feat_all",
    N = 30,
    check_replicable = FALSE)
  expect_true(result, info = result$error)
})
