This is a follow-up of https://github.com/docker/cli/pull/4419. That PR
leveraged the fact that EndpointSettings.MacAddress is already
available, although not used by the CreateNetwork endpoint.
TestParseWithMacAddress was testing whether the container-wide
MacAddress field is set, and we still need to test that to ensure
backward compatibility. But we now also need to test whether the
endpoint-specific MacAddress is set.
