fix: ensure cleanup of service

Previous fix in 26c7177 did not ensure cleanup of the service if the
TestServiceUp call failed. This would lead to situations in which
cluster deletion would fail in the TestCreateClusterWithFargateService
integration test because the cluster still contained an "active" service.
