Added "use Try::Tiny" to fix Try::Tiny not being included as dependency

We had an issue with a broken Moose install on one of our machines (for some reason none of its dependencies were installed).  However when we were trying to install MooseX::NonMoose it was failing the tests due to Try::Tiny not being in the dependencies yet being called cirectly in one of the modules.  Adding a "use Try::Tiny" fixes this and allows dzils AutoPrereqs to pick up ther requirement.
