Fix verify_service method namespace conflict.

When running "bundle exec rake full[1]" all of the specs are loaded and
BVT::Spec::CanonicalHelper and BVT::Spec::ServiceLifecycleHelper are both
included at the top level. This causes specs intending to call the canonical
verify_service to fail because the two have different signatures.
