WrappedListener handles this optimization internally

What about also adding an assertion to the test which checks that the event instance passed to the listener actually is an instance of the ContractsEvent?

the event instance passed to the listener actually is an instance of the ContractsEvent?

implementing this interface is not a requirement

Assertion added to ensure that the event passed to the listener is the same as the dispatched one (and not a proxy), also rebased to make the CI green.
