ParamSet dependencies are not properly deep cloned

[pfistfl]

I guess the following should work:

  library(paradox)
  ps = ParamSet$new()
  ps$add(ParamFct$new("a", levels = letters[1:3]))
  ps$add(ParamFct$new("b", levels = letters[1:3]))
  ps$add_dep("a", "b", CondAnyOf$new(letters[1:2]))

  ps2 = ps$clone(deep = TRUE)
  expect_deep_clone(ps, ps2)

I get the following error: Error: Object addresses differ at path ROOT->[element .enclos_env] '.enclos_env'->[element private] 'private'->[element .deps] '.deps'->[element cond] 'cond'->[element 1] isn't true.

expect_deep_clone is from here
