negated_normal decomposes global constraints #285

In negated normal global constraints get decomposed, I think this does not make sense, as we have decompose_global() for this now.

ie: print(flatten_constraint((~AllDifferent(iv).implies(AllDifferent(ivv)))))

The second AllDifferent gets decomposed here, but we could also have a flat output like this, which seems cleaner:

bv0 = AllDifferent(iv), ~bv0 -> AllDifferent(ivv)
