[bug] PropertyTestUtil should not enforce order for collections

The test cycle for collection-like properties worked only for
collections that retain their ordering of entries during an add
or remove operations, which for example HashSet does not.

Relaxed the equality check so that ordering of elements does no
longer play a role.
