Fix climb-back-hierarchy hack to work with latest MooseX::Role::Parameterized

After upgrading MooseX::Role::Parameterized all my model test started to fail and I was also able to se it failing on Mongoose tests. This small fix allow Mongoose to work with new version and keep compatibility with old ones.

I've also seen another bug when running tests that looks something with DBref's, this was failing before my fix and are still failing. I'm trying to understand that problem, but we are not using dbref's.
