Integrations tests (#408)

* Add cfg and verUSDC to deployments where applicable

* add cfg and cerUSDC to all deployments. Build out test

* fix tests

* update tests

* add comment explaining unset_address constant

* fix tabs in deployments. Use try/catch in tests

* move try/catch to its own function
