Element global constraint accepting lists leads to error in linearize constraint

[Wout4]

Bug found while fuzztesting on linearize_constraint

minimal example:

cons = [Element([1,5,3,4],iv[0]) == 6]
linearize_constraint(cons)

possible fix: make array in Element constructor

Closing as the new linearize function should not decompose any global constraints.
Either they are decomposed using decompose_global or the constraint is supported and should fall through the entire transformation.
